The African Queen is an old, dirty, ugly, unreliable steamboat. No one would take a boat like that down a dangerous river through the jungles of Central Africa during the First World War. But Rose Sayer and Charlie Allnut do just that. They come close to death many times, but no one would expect a missionary's sister and a rough, uneducated mechanic to fall in love . . .The film of this famous love and adventure story, made in 1951, starred Katherine Hepburn and Humphrey Bogart, and went on to become one of the most popular films ever made.
