According to Reuters, Yoko has teamed up with Lennon's sons to file suit against the producers of "Expelled: No Intelligence Allowed" because they used Lennon's song "Imagine" in the film. The documentary film deals with academic and scientific discrimination from Darwinists against intelligent designers.

The filmmakers claim that the fair use doctrine comes into play since they were using the Lennon track for commentary. "We are disappointed therefore that Yoko Ono and others have decided to challenge our free speech right to comment on the song 'Imagine' in our documentary film," they said in a statement.

According to a wikipedia entry: "Intelligent design is the assertion that 'certain features of the universe and of living things are best explained by an intelligent cause, not an undirected process such as natural selection'. It is a modern form of the traditional teleological argument for the existence of God, modified to avoid specifying the nature or identity of the designer."
