A little bit more trivia with regard to the the boat itself: In 1954 Ernest Hemingway (who was a friend of director John Huston) and his wife Mary were on safari and were aboard a plan that went down near Murchison Falls in Uganda. No one was injured, but Hemingway and his entourage had to wait out the night until they could flag down a boat. The boat that came to their rescue was the same boat Huston had used in shooting the African Queen. The boat took them to Butiaba where they boarded another plane which also crashed, this time while taking off. The Hemingways survived again, but sustained some serious injuries that time. The full story can be found in the recent biography of Hemingway by Mary Dearborn.
