Nominated for 10 Oscars, the movie depicts the true story of white settlers who systematically murdered wealthy members of the Osage tribe in Oklahoma in the 1920s. In northern Oklahoma, just minutes from the Osage Nation, high school English teacher Debra Thoreson says because of new laws in the state she is too nervous to teach the popular book on which the movie is based. Thoreson told ABC News' MaryAlice Parks on "This Week."
