"Spider-Man 4" to star the corpse of Charles Bronson?

There is a rumor going around town that the dead corpse of Charles Bronson is going to be used for a "dummy-figure" in a scene where Venom violently mutilates a body. Whether there is any truth in this, it has been confirmed that Toby Maguire, J.K. Simmons, and Kristen Dunst will NOT return.
