When Rhodey (Don Cheadle) talks about how he fired Nick Fury (Samuel L. Jackson), he makes a wrestling reference by saying "he DDTed the dude from the top rope and that it was Undertaker level." The DDT is a move that was actually invented and made famous by wrestler Jake "the snake" Roberts. The Undertaker (Mark Calaway) is known for using the tombstone pile driver to finish is opponents.
