Big Lipped Alligator Moment: It wouldn't be an Ed Wood film without one. This one ends with a nuclear explosion for no reason at all, except for executive producer Donald McCoy insisting the film end with one.
Special Effects Failure: The octopus stands out; supposedly the crew either forgot the motor that made the limbs move or couldn't afford to hire it, resulting in the actors having to flail around and make it look like they were being attacked. Surprisingly enough, Ed Wood actually doesn't do too bad a job of working around this problem in the first and last scenes where we see the octopus, using quick editing along with rain and lighting effects to obscure how unconvincing it looks. Unfortunately, the same can't be said about Dr. Strowski's death scene, every second of which looks laughably fake.
Tear Jerker: Despite the shitty dialog and plot, Bela Lugosi still shows his acting chops and goes out in style.
