Revealing mistake: In the scene where Herbert and Dan re-animate the dead corpse, watch closely when Herbert rams the little buzz saw into the corpse's chest. At the bottom of the screen, you can see where the fake chest ends.
Continuity mistake: The glass window in the door to Dr. Hill's office is broken so that the main character and his girlfriend can enter. Later when Dr. Hill and his severed head return, the glass is perfectly fine.
Trivia: The theme music of "Re-Animator" is a deliberate adaptation of the theme music from Alfred Hitchcock's 1960 movie, "Psycho," originally composed by Bernard Hermann. In the Millennium edition DVD of "Re-Animator," composer Richard Band said that his "Re-Animator" score is a tribute or homage to Bernard Hermann's "Psycho" score; this fact was supposed to be noted in the "Re-Animator" credits, but was accidentally omitted, leading to more than a little confusion and controversy among fans for decades.Charles Austin Miller
Herbert West: I know your work, Dr. Hill. Quite well. Your theory on the location of the will in the brain is... interesting. Though derivative of Dr. Gruber's research in the early 70s. So derivative in fact in Europe it's considered plagiarized.
