The film's co-stars were hounded by questions about their relationship at the premiere at the Toronto International Film Festival. The couple offered the standard "no comment" to all personal questions.

"All I will say is that we work very well together," Danes said.

But Stage Beauty director Richard Eyre acknowledged their relationship to Entertainment Weekly. He said it was apparent during filming that the two "got on very well."

Stage Beauty is set in 17th-century England when men assumed female roles in plays. Crudup spends much of the movie in drag as a stage star considered the most beautiful leading lady of his day.

Danes plays an ambitious wannabe actress who falls in love with him, but is jealous of his success.
