The movie features an Ark similar to the one in the I.J. movie, the Prof resembles Sallah in appearance and voice/accent, there are greedy Gestapo-like military men competing for the treasure and the power it will supposedly bring, the treasure turns out to be worthless money-wise, using the lens-cap in place of the gold coin to keep the booby-trap from activating the same as Indy uses a bag of dirt to replace the golden idol, and so on.
