- The opening sequence employs heavy references to the 1981 film Raiders of the Lost Ark. Dr. Orpheus is wearing the same ceremonial robes that Belloq wears when they open the Ark towards the end of the movie. Also referenced is when he tells Dean to "not look at it, no matter what happens." This is the same instructions Indiana Jones gives to Marion when the Nazi's open the Ark. When Dr. Orpheus unleashes the magic lightning from his staff, his destruction of the Nazi's holding Dr. Venture hostage mimics the scene where the Nazi's are killed by the Ark of the Covenant. The two guards are pierced by the magic lightning and their leader even exclaims "It's beautiful," just before his face melts off in the same manner as Toht.
- A Wilhelm Scream is heard when Brock jumps out of the OSI flying headquarters and lands on a trooper using a jetpack.
