it's recent (2004). the beginning of the movie is set in the 1960s and one of the soundtracks is "somebody to love" by Jefferson Airplane.
I liked the movie. It was interesting and different. I like Colin's acting in it. Saw it a long time ago in theater in Minneapolis.....Thank you for reminding of it. Good song though.
i've read the book - it's really fantastic (the author, Michael Cunningham, also wrote The Hours)....didn't even know they made a film...sounds like it's worth checking out though
