but there's a backlash. tonight, why it's not all happy on the home front. plus, american hustlers. amy adams and christian bale on what it took for them to say yes to what turned out to be one of the hottest movies this awards season. and how this bad hair and these low cut dresses just might lead to oscar gold. and big mac. >> i would like to show you macintosh in person. >> many inventions never live to see their 30th birthday. but today, the computer that changed the world turned the big three-oh. >> the next ones are going to be even better. good evening. and thanks for joining us. imagine this -- men stay at home doing the house work while we women go to work. forget the backlash over stay at home moms. now it's stay at home dads under fire. that's right, trophy husbands are ruling the playground as their high-powered wives stake out the corner office. so is dad the new mom? >> jake howard potter is used to being a fish out of water. >> what are some of the things you guys do in class? >> floating on our back. >> he's been a stay at home dad for almost four years. >> mommy! >> is that her? i don't think so. >> we were with him two years ago when his daughter skyler was still in diapers. today he has his hands full with the new addition, 8-month-old lyndon. >> it's really just amazing to watch and be a part of. i'm definitely still enjoying it. it's quite a bit more work than i had anticipated. it's very difficult to be in more than one place at one time. >> he does everything a mom would do, from swim class to nap time. >> night, night take a nap. >> there are certainly a lot more fathers that are a lot more involved. because it's become much more prevalent in the media, because it's been written about more, buzz there's more people doing it, i think it's much less weird dad on the play ground with a kid. >> it wasn't long ago that they were portrayed as bungling mr. moms. like the clueless guys from "three men and a baby" who couldn't figure out how to change a diaper. but today's stay at home dads are geared up and pushing strollers with pride. like the dudes group from "what to expect when you're expecting." >> in reality, people sort of think of, you know, stay at home dads at the bumbling mr. mom from the movies. whether that's a setup by hollywood and then has been reinforced by the public, it's certainly something that i considered when i decided to be a stay at home dad. you know, all that being said, i challenge anybody that's sitting in an office for eight hours a day to come try to do what i do with these two kids on daily basis. >> but it's not all play dates and playgrounds. stay at home fathers can still be a target for ridicule. just last month, a doting dad uploaded this photo of himself doing his daughter's hair. it went viral. some women swooned. but the haters came out, too. with ugly comments. he probably rented those kids. they don't even look like him. or i would bet anything that you're a deadbeat. but his simple message was a blog post called i have a dream that people will view a picture like this and not think it's a big deal. tom stockey shares that dream. he took four months off from his job at facebook to care for his newborn daughter. >> she would find new things to try to eat, new things to try to stick her fingers into. there was dangers loom on all sides. >> but he was surprised by all the unsolicited comments he got, often snarky, that he got. >> stockey vented on facebook about comments slamming moms who work when dads don't. one stranger cracked, it's too bad you can't earn as much as your wife so she can be the one to stay home. >> i think it's a traditional gender stereotype that we all buy into to some extent that mommys are better at daddies. >> mommys are better at that kind of mommying than daddies. >> lisa miller wrote a controversial piece called retro wife where she says women shouldn't feel bad about opting out of their career. >> this idea that you have to go out as a woman and, you know, be ambitious and be driven and play with the big boys, that's a very specific message for a very specific kind of woman. most women, and i would venture to say, most people, don't have that kind of ambition. and are never going to make that kind of money. naen lig and in light of that, what is the harm in deciding to stay home with your children. >> on the flip side, stay at home dads have to fight the perception that they're mooching off their white's salary. >> most people think i'm a bum. i should be out there working, why is my wife working, i'm not working. and i'm like, i am working. if it was reverse you wouldn't say she's a bum you would say oh, what a great mother she is. i'm a great father. >> for a lot of stay at home dads, it is strictly a number the game. their wives outowner them. jake is an artist and his wife is a tax lawyer. >> say bye-bye. >> we spent the day at her office before baby number two. >> i can sit and be a lawyer and be very focused and sit at a desk and, you know, i'm a tax lawyer. so i can look at tax returns and change numbers. this changes this number. this is not the way his mind works. and it's very frustrated to him. >> the women like erica who bring home the bacon are often criticized for not being home with their kids. on this night, she had only 30 minutes of mommy and me time. >> a lot of women i know, even hardworking, ambitious, out in the work force women hold this idea that unless they make the sandwich, the sandwich isn't as good. >> marriages like jake and erica's are still in the minority. even though the number of at-home dads doubled in the past ten years, it's still a small number, less than 200,000. working ma mom beyonce sings around running the world. ♪ who run the world ♪ girls >> she cently weighed in on an editorial on working women. we need to stop buy into the myth about gender equality. it isn't a reality yet. the average working woman earns only 77% of what the average man makes. men have to demand that their wives, daughters, mothers and sisters earn more. so why are we viewed as less equal? >> the most stressful thing on a marriage is when people are living roles that they didn't expect. they will find it emasculating if they have an idea of themselves as the knight in shining armor, the breadwinner. >> but for jake, there's nothing unmanly about being a dad. >> in some ways, guys who stay home with their kids are actually even more manly. they're kind of able to put their egos aside and really do what's necessary to take care of the kids. >> makes you rethink things. coming up next for us, the a-list stars of "american hustle" give us the real story behind the hottest movie this awards season. the recent increase in cafeteria prices is not cool. when you vote for flo, we'll have discounts. ice-cream discounts. multi-cookie discounts. pizza loyalty discounts!

more than $100 million earned at the u.s. box office. ten academy award nominations. including ones in each of the four acting categories. proof that "american hustle's" appeal is no con job. >> he wasn't necessarily in good shape and he had this comb over that was rather elaborate. >> for best actor and best actress nomineeshristian bale and amy adams. their con artist's couple secret weapons, the way they get potential marks to fall for a scam is by first telling them no. >> the key to people is what they believe and what they want to believe. >> i think that when you say no, it creates allure and it makes people more curious. i think that can happen in relationships as well. the more people push you away, the closer you want to get to them. >> can we talk business. >> it's that taboo. i discovered that working in films as well. when you turn something down, they keep coming back with better offers because they don't really believe you. >> i was there the whole time. you don't really know it. y become somebody people can pin their dreams on. >> now almost 40, bale initially turned down the chance to play irving rosenfeld on the movie based on the scams in the 1970s until bale's spouse stepped up for him. >> i said i don't have the time to do this properly. and my wife got on the phone and she said, he will talk out of everything. just ignore him. he can do this. thankfully she was right and i thank you very much for having sorted that out. >> we've got to get over on all these guy ps . >> adams found herself drawn in by the vision of her character, scripper turned grifter sidney that rus shell shared in their initial meeting. >> he said i want her to be the smartest person in the room. i want her to be just a survivor, and i really keyed in with that. >> you're going to have to decide for yourself, kit. i just laid everything on the table. >> strength is so much fun to play for me. it's so much fun to be the person who doesn't care what anybody else thinks because it's just so not who i am. >> bale cast aside his dark batman silhouette, messed on his hairline and packed on some 50 pounds, thanks to the real life con man who partnered with the fbi to catch dirty politicians. >> i was greatly inspired seeing members of earl wineberg. he's a charming figure who sort of waddles. i said i have to pursue, i have to ask for that man. it just became me saying i don't see how to play it without looking that way. >> what's the "s" stand for. >> for her character so different from lois lane in the man of steal or "her's" lonely game designer. she decided she would say yes to the dres. >> i could only dream about these dresses they're beautiful. >> and no to pretty much anything beneath it. daring to bear first urged on her by custom designer michael wilkinson. >> he was smart. there was a sort of confidence that happens because your posture has to change to keep everything in place. the idea in her mind is if men aren't paying attention to the details when they're distracted, maybe they won't ask as many questions. >> adams and bale worked together before on a david russell film "the fighter" which bale won a best supporting actor oscar. >> we didn't have that many scenes together in "the fighter" but the good thing is we've been through the process with working with david. we know what to expect. >> the first time i worked with him, he was sending texts during a table read about his ideas about my character. i thought oh, my gosh, he hates what i'm doing when really he was just excited and coming up with ideas. 24 hours a day david is texting you. so you are really committed. >> you don't ever just turn it off and say -- >> i do. i have a kid. >> a lot of actors like to be very controlled, know exactly what's happening. and i'm not that kind of actor. i like it to be very spontaneous. i don't mind saying it's chaotic. i don't know if david would appreciate hearing that word used. and i think you really strike gold sometimes when you have that attitude. >> he died this year. he saved my life many time 37s. >> mine, too. >> during preproduction that song "jeeps blues" would send adams into a private reverie that russell and her co-star bradley cooper would witness. >> did you come upon amy adams dancing to that duke ellington song in your production song at one point? >> yes. and there's amy with the lights kind of off dancing like ann-margret in my office. >> there's things you don't think people will talk about. and then it's revealed you're doing a dance number in a production office. >> each powering these american hustle oscar nominated perform mans. and lessons from bale's real-life role m.d. odel. >> you believe what you believe as you're doing it. and to be a con man, you have to have a big set of balls, you know?
