[li]It was in black and white[/li][li]It was most likely released between 1955 and 1957[/li][li]An airliner carrying passengers has a hard landing in a cannibal-infested jungle (Brazil?)[/li][li]After repairs(?) the plane can fly again but at a reduced capacity[/li][li]Guy with a gun persuades the pilot to take an additional two or three passengers with him[/li][li]Guy with a gun remains behind with the other lunch candidates as the plane takes off[/li][/ul]
