I've started reading Hubert Selby Jr's fabulous novel Requiem for a Dream the other day. I found it in a Booksale bin, and never let go. Darren Arenofsky's film of the same title was based on this one, with the screenplay also written by Selby. I have nothing but praises for this one, and Ellen Burstyn should have won that Oscar. But we all know who took it home. Feh. Anyway, I haven't seen Pi yet, his first film, but on the basis of Requiem, I'm almost totally sure that it was just as paranoid and disturbing.
