Agent: You talking to me?
Andy: Yes, I'm talking to you! Didn't you read the play?
Agent: What play?
Andy: The play I'm in, the play that you got me a part in. It's a gay play. I've got to play a gay, with another gay. Acting all gay. All through the play, it's so gay!
Ian McKellen: How did I know what to say? They had my lines written down on a script. How did I know where to stand? People showed me.

Andy: It's like bloody Deliverance...
Deliverance is a 1972 film that is shot primarily in the rivers and woods of Appalachia. In the film's most psychologically terrifying sequence a sexually-perverted Appalachian native humiliates the character of Bobby (a chubby-faced, defenceless man). He forces the man to first strip down to his underwear. He then makes Bobby squeal like a pig before sodomising him.
