Will & Grace made Eric McCormack a star. In Alien Trespass, a Matinee-style homage to classically cheesy science-fiction flicks, he plays noted astronomer Ted Lewis, who gets possessed by Urp, an alien marshal trying to track down a rubbery, marauding blob in his custody after they crash-land on Earth. I spoke with McCormack recently about the touchstone inspiration of various old movies, whether people have stopped assuming he's gay, the future of TNT's Trust Me, and how kids — including his son — say the darnedest things.
