Hey, It's That Guy!: The film's star Daniel Bernhardt plays one of the upgraded agents in The Matrix Reloaded (the one who fights Morpheus on the truck). It's both frightening and uplifting to know that this movie didn't kill his career.
The old guy with the Hawaiian shirt is legendary science fiction fan and Vampirella creator Forrest J. Ackerman. He was apparently too distracted reading a copy of "Famous Monsters of Filmland", the magazine he edited for 25 years, to notice the dinosaur that killed him.
