The nuked refrigerator scene in Indiana Jones and the Crystal Skull is the best scene in that entire movie. Despite being ridiculous, it’s the only scene with a distinct 1950s personality befitting the premise of the film. The majority of the rest of the movie is just a bland rehash of chase sequences from earlier films set in a non-descript boring jungle, and could easily be transplanted into the 1930s if you swapped out the Soviets for Nazis and the glass skull for whatever. Instead, the movie should have taken Indy to East Berlin, and eventually culminated in an action sequence at a secret Cosmodrome in Kazakhstan.
(Alternatively, Indy should probably not exist in the 1950s, because Cold War Indiana Jones starts to closely approximate James Bond if you stray too far from the ancient civilization archeology angle, yet the “adventurous archeologist” trope is anachronistic after British colonial rule in the Mid-East begins to collapse.)
Haven’t seen Crystal Skull in a long time but this is all true.
