33. Indiana Jones and the Kingdom of the Crystal Skull (2008)
Don’t blame Harrison Ford, who was a spry 65 when he shot this fourth Indy adventure. It’s the rest of the film that’s a mess: we get Mayans, kung-fu assassins, extraterrestrials, giant ants and that fridge, which protects the hero from an atomic blast in the most widely mocked scene of Spielberg’s career.
