UPDATE: For a further dissection of the theory, check out my conversation with Roth Cornet here.
When Indiana Jones and the Kingdom of the Crystal Skull was released in 2008, critics and general moviegoers were sharply divided on the film, which finished with a 78% “Fresh” rating on Rotten Tomatoes despite pulling an audience rating of only 54%. Perhaps the most reviled moment was the infamous scene where Indy survives a nuclear blast by hiding out in a lead-lined refrigerator, which went on to inspire the “Jump the Shark”-esque term “Nuke the Fridge.” (Note: the scene in question was originally included in Frank Darabont's rejected-by-George-Lucas script for the sequel, but both Lucas and Spielberg have separately taken the blame for keeping it in the finished film.)
And yet according to a very interesting new fan theory, the globe-jumping archaeologist may have been able to survive the unlikely scenario thanks to the scene in Indiana Jones and the Last Crusade in which he drinks from the Holy Grail. From Reddit user That_secret-chord:
Food for Thought: Indiana Jones drinking from the Holy Grail helped him survive unlikely scenarios, most notably the infamous fridge scene.
It's a good theory! Doesn't explain away the horrific “Shia LaBeouf swinging with the monkeys” scene though.
