The Burning Secret is a Stanley Kubrick project that was never completed. Harris and Kubrick (after being turned down by MGM to film Paths of Glory) found Stefan Zweig's novel The Burning Secret, a book about a young baron trying to seduce a Jewish woman by befriending her twelve-year-old son. Kubrick hired Calder Willingham to produce a screenplay.
The film would be impossible to make accurately due to the Production Code restrictions at the time. This was also the reason for the cancellation of another earlier Kubrick project, Natural Child, which would be based on a Calder Willingham novel.
