Die-hard Indiana Jones fans tend to dislike Kingdom of the Crystal Skull but the movie was clearly made with them in mind.
The film opens with Indiana Jones (Harrison Ford) reluctantly helping a group of Russians as they scour Area 51 for alien remains.
When Indiana Jones tells Mutt Williams he once met Pancho Villa, it’s a cute line — and a reference to the TV show The Young Indiana Jones Chronicles, where that did indeed happen.
Legacy is important to every Indiana Jones movie; the title character is an archaeologist by trade.
