One of my favorite moments in "Galaxy Quest" takes place as a Red Digital Readout is ticking off the second until a spaceship is blown to smithereens. The only person who can save it is a teenage science fiction fan far away on Earth--and he has just been ordered by his mother to take out the garbage. But then the ship is saved! How? I won't spoil the moment, except to say the ship is modeled in every possible respect on a ship that appears on a TV show, and that includes a digital readout that is also consistent with TV cliches.
