Humphrey Bogart won his first and only Academy Award for Best Actor for his unforgettable performance in “The African Queen” (1951). Bogart stars opposite Katharine Hepburn in a tale of adventure and unlikely romance. After a religious spinster's (Hepburn) missionary brother is killed in WWI Africa, a dissolute captain (Humphrey Bogart) offers her safe passage. She's not satisfied, so she persuades him to destroy a German gunboat. The two spend most of their time fighting with each other rather than the Germans. Time alone on the river leads to love.
