Have you heard the urban myth that C-3PO, Princess Leia and R2-D2 appear in Raiders of the Lost Ark?
It’s not a myth. They do feature. In fact, there’s a lot connecting the two films beyond the fact that the scene in which Rene Belloq and the Nazis square off against Indiana in the canyon is the same location as the Tatooine scenes from A New Hope.
Check out the registration number of Jock’s plane at the beginning of the film. It’s “OB-CPO” which is believed to be a reference to Obi-Wan Kenobi and C-3PO. However, an even stronger connection is the name of the club in which Willie Scott sings at the start of Temple of Doom. It’s called “Club Obi-Wan“.
As for R2-D2, Leia and C-3PO in Raiders? They appear as hieroglyphics in the Well of Souls.
