Revealing mistake: When Hellboy drops the giant cog on Kroenen and kills him, there's a bizarre mistake. As the cog falls towards camera, it sort of half-rotates in mid-air and you can see Hellboy in one of the little gaps for about one second. And you can see him standing above... holding the exact same giant cog that is currently falling towards camera. According to the YouTube series "VFX Artists React," it's likely the result of the VFX program just looping the footage to insert behind the cog.

More quotes from Hellboy
Trivia: The BPRD complex was (according to Del Toro) was originally FDR's secret emergency bunker. The library where Professor Broom dies was the president's office and Hellboy's room (with the big vault door) was his fallout shelter, just in case Germany perfected the A-bomb first.
Question: Why does Kroenen turn that key on his body? I thought it would be to help increase his speed but, he is very fast without turning it.

Answer: The internal machinery that powers him is clockwork. It needs to be wound like a watch every so often. He releases most of the tension when he fakes his death.
