Finding Nemo is a new Walt Disney/Pixar feature that tells the comic tale of two fish: Marlin, a clown fish, and his only son, Nemo, who are taken from their Great Barrier Reef home and thrust into a fish tank in a dentist's office overlooking Sydney Harbour. Jim White talks to the writer and co-director Andrew Stanton about the art of animation, Pixar-style. Also on the programme, Ewan McGregor and Tilda Swinton on their performances in Young Adam, a film adaptation of Alexander Trocchi's novel, set on a coal barge in 1950s Glasgow.
