The Adventures of Baron Munchausen is a 1988 adventure fantasy film, co-written and directed by Terry Gilliam, starring John Neville, Sarah Polley, Eric Idle, Jonathan Pryce, Oliver Reed, Robin Williams and Uma Thurman. An international co-production between the United Kingdom, the United States and Germany, the film is based on the tall tales about the 18th-century German nobleman Baron Munchausen and his wartime exploits against the Ottoman Empire.

The film was a notorious box office bomb, grossing just $8 million, losing Columbia Pictures $38 million. Despite this, it received positive reviews from critics and was nominated for four Academy Awards: Best Art Direction, Best Costume Design, Best Visual Effects and Best Makeup.
