Karen Allen is the actress best known for the role of Marion Ravenwood in the Indiana Jones franchise. In the scene where Marion is pushed and falls in The Well of the Soul, Marion's white open-toe high heel shoe falls off her foot into a pit of snakes. She then lands on the lap of Indiana Jones (portrayed by Harrison Ford), while the shoe is on top of poisonous snakes. They show one of the snakes slithering through the open toe of her shoe. There are nice shots of her one shoe condition follow, as she tries to keep snakes away from her all while wearing one shoe.
