4. Doom Explodes Tim Blake Nelson's Head & Kills Countless Soldiers
When Doom breaks out of his restraints, one of his first actions is to kill Dr. Allen (Tim Blake Nelson), by grabbing him and causing his head to explode inside of his hazmat suit. So much for those rumours of him being Mole Man, right? Doom then walks along the hallway, deflecting bullets out of his way, slamming soldiers against the walls and exploding even more heads, leaving bloodstains all over the walls. It's surprisingly grim stuff for a PG-13 movie, though is sadly rendered utterly soulless because the audience just isn't invested in what's going on.
