Eating Raoul is a cult classic film from 1982 starring Paul Bartel and has absolutely nothing to do with this cache...it's just what pops into my head when I think of the name Raoul.
From Wikipedia: Raoul Wallenberg was a Swedish diplomat and a member of the influential Wallenberg family. In the later stages of World War II, he worked tirelessly and at great personal risk to save many thousands of Hungarian Jews from the Holocaust. He was later arrested by the Soviets who suspected him of being a spy; the circumstances of his death while in their custody are still a matter of great controversy.
