Battle Circus is a 1953 war film directed by Richard Brooks, who also wrote the screenplay. The movie stars Humphrey Bogart and June Allyson, and costars Keenan Wynn and Robert Keith.
The film is set in Korea during the Korean War. Bogart (in his sole film for Metro-Goldwyn-Mayer) plays a surgeon and commander of Mobile Army Surgical Hospital (MASH) 8666 (shortened to "66" in the dialogue), with Allyson playing a newly arrived nurse. Despite their initial handicaps, their love flourishes against a background of war, enemy attacks, death and injury.
