Sienna Miller (Factory Girl) and Cillian Murphy (The Wind That Shakes the Barley) have signed on to star in Hippie Hippie Shake (wow, that's two 'shake' movies for Murphy). The film is based on Richard Neville's memoir and will be directed by Beeban Kidron (Bridget Jones: The Edge of Reason).

Neville's book provides an inside look at the 1971 Oz obscenity trial which was, at that time, the longest obscenity trial in British history.

Neville and his co-defendants Jim Anderson and Felix Dennis were charged with conspiracy to corrupt the morals of young children and young persons. The issue of Oz magazine in question was known as School Kids and was actually put together by real school kids in response to charges the magazine's editors were out of touch with the younger generation. The defendants were convicted but their sentence was overturned on appeal.

Max Minghella and Emma Booth have also joined the film which is expected to begin shooting this fall.

Cillian Murphy will next be seen in Watching the Detectives with Lucy Liu and the sci-fi film, Sunshine, directed by Danny Boyle.

Sienna Miller recently completed work on The Mysteries of Pittsburgh and has a small role in Matthew Vaughn's Stardust.
