Christopher Plummer's latest role in 'Beginners,' is somewhat of a departure. He plays the father of Ewan McGregor who has two big announcements -- that he has terminal cancer and (surprise!) he's gay. It's a lovely, bittersweet movie with yet another winning performance from the 81-year-old Canadian. In a chat with PopEater, the beloved stage, TV and film actor spoke about the motivation behind his latest role, then dips into the past by defending his decision to turn down the role of Gandalf in 'The Lord of the Rings' (too much time commitment) and becomes flustered when reminded of fans' enduring obsession with the most visible film in his 100-film-plus catalog, 'The Sound of Music.'

"Yeah, it drives me nuts," he says about all the fuss over the 1965 film. "It has nothing to do with the movie, it's just a relentless pursuing of this film that goes on and on and I've gone on and on, far above and beyond it and then to be reminded of it. God almighty what is the matter with people?"
