Put yourself, for a moment, in Anthony Edwards' shoes. As a lead actor in "ER," you star in one of the biggest TV shows of the last decade. You've already proved you can deliver on the big screen; people still talk of your scene-stealing role as Tom Cruise's sidekick in "Top Gun." The Hollywood studios know this; each year before "ER" takes its summer hiatus they're on the phone to your agent, trying to interest you in movie roles.
