Anyone capable of telling the difference between a bantha and a ronto will know that StarWars’ C-3PO and R2-D2 appear in hieroglyphic form on a wall in Raiders of the Lost Ark. But you might not know that Harrison Ford carried a bullwhip in The Empire Strikes Backas a nod to Indiana Jones a year before Raiders of the Lost Ark was released. Or that a Nazi tank appears in The Phantom Menace. Fortunately, Today I Found Out’s Tegan Jones has compiled a list of these Indiana Jones / Star Wars crossover easter eggs, and many more.
