A few months ago, the evolutionary biologist Richard Dawkins received an e-mail message from a producer at Rampant Films inviting him to be interviewed for a documentary called “Crossroads.”

The film, with Ben Stein, the actor, economist and freelance columnist, as its host, is described on Rampant’s Web site as an examination of the intersection of science and religion. Dr. Dawkins was an obvious choice. An eminent scientist who teaches at Oxford University in England, he is also an outspoken atheist who has repeatedly likened religious faith to a mental defect.

But now, Dr. Dawkins and other scientists who agreed to be interviewed say they are surprised — and in some cases, angered — to find themselves not in “Crossroads” but in a film with a new name and one that makes the case for intelligent design, an ideological cousin of creationism. The film, “Expelled: No Intelligence Allowed,” also has a different producer, Premise Media.

The film is described in its online trailer as “a startling revelation that freedom of thought and freedom of inquiry have been expelled from publicly-funded high schools, universities and research institutions.” According to its Web site, the film asserts that people in academia who see evidence of a supernatural intelligence in biological processes have unfairly lost their jobs, been denied tenure or suffered other penalties as part of a scientific conspiracy to keep God out of the nation’s laboratories and classrooms.
