Helm's death was longer before the film was trimmed to avoid an X rating. Originally, Helm was supposed to be gutted from crotch to sternum, but that was removed, and creates a continuity error, according to the IMDB:
Continuity: During the fight at "The Last Resort", Thumbelina stabs the goon with glasses in the stomach. When the camera pans out, the knife and blood are coming out of his chest (originally, the goon was supposed to be gutted from crotch to sternum, but was edited out for the R-Rating).If any of you own an issue of Fangoria from around the time of the film's release, they included a few stills of this in that issue.
