Deliberate mistake: When Violator turns back into Clown in the alley, watch closely. You can see his shadow beneath him for a few seconds as he's transforming, and it doesn't match the transformation of the giant monster into the Clown... it's just Clown's regular shadow from the actor standing on-set. More than likely, it's a shortcut for the effects - they didn't bother rendering a simulated shadow. You have to look kinda close to notice it the first time, but once you see it, it's obvious.
