Night Fright is a 1967 American science-fiction horror film directed by James A. Sullivan that was shot near Dallas, Texas.
The Texas community is soon beset by a rash of mysterious killings, including of students from the local college who wanted to throw a party at the spaceship crash site.
When Sheriff Clint Crawford (John Agar) investigates the deaths he discovers the startling identity of the killer, an alligator mutated into an ogre-like creature.
Scientist Professor Alan Clayton (Roger Ready) is called in to assist law enforcement and the mutant is eventually killed by luring it into a dynamite trap.
noting the monster design was a plus and John Agar does a good job as the sheriff, but overall the film is dreary and deserves its obscurity.
