"Something's going to happen in this movie, which I hope happens in all the movies I do," teased Costner of No Way Out's surprise twist ending. "They're going to have to think about this one; this is an old-fashioned movie for me in the notion that you show up, you don't know what it's about, and when it's all done, it was worthwhile -- something really happened -- and that's what a good movie is to me."

The Roger Donaldson suspense film cast Costner as Tom Farrell, a navy officer whose steamy affair with the mistress (Blade Runner star Sean Young) of the defense secretary (Gene Hackman) threatens to blow up in his face when she's found dead.
