The Dreamers (2003)

Bernado Bertolucci's film, scripted by Gilbert Adair from his novel, and set in 1968, stars Michael Pitt as an American student who enters the lives of Parisians Theo and his sister Isabelle. The three share a love of the movies but soon their relationship is one of sexual entanglement. The film's plot is counter-pointed with extracts from classic films that almost act as a Greek chorus on their relationships, while the trio's reality is affected by the growing unrest on the streets.
