Behind the scenes
- "Dr. Fantasy is a great party host, and a master of several complicated high dives into large cakes."
- ―Harrison Ford[src]
"Doctor Fantasy" was an identity Indiana Jones producer Frank Marshall adopted when performing magic shows during crew parties. After accidentally falling into a cake during the wrap party for Raiders of the Lost Ark, it became a tradition for Marshall (as Doctor Fantasy) to dive into cakes as a part of parties during the making of Indiana Jones and the Temple of Doom and Indiana Jones and the Last Crusade. The name on the caboose is a reference to Marshall's "Lucasfilm tradition".
