Eric McCormack relishes role as Broadway villian

(CBS News) Though best known as "Will" on "Will & Grace," Eric McCormack now appears as the ego-driven villainous senator in the Broadway revival of Gore Vidal's "The Best Man."

"Sunday Morning": Eric McCormack: Now playing the bad guy

McCormack joins an all-star cast, which includes Angela Lansbury, Candice Bergen - and James Earl Jones, perhaps best known for voicing Darth Vader in the "Star Wars" movies.

"It's totally fun," McCormack said. "To be on stage with James Earl Jones and realize I'm the bad guy. He's Darth Vader, but I'm worse."

The play, based on the deadlocked 1960 national convention in Philadelphia, has particular relevance considering the current campaign trail antics, McCormack said.

"It feels like nothing has changed," he said. "That's just enlightening and depressing. It truly is. ...Part of (the play's relevance) is how brilliant a writer Gore Vidal is, and the other is just the coincidence of everything the GOP does every day. Something they say, the Etch-a-Sketch moment last week. I mean, there's a joke in this play of contraception and Catholic Church that two months ago would have been an ancient reference, and now is completely timely, which is bizarre and sad."
