Giant mutant rabbits - The worst nightmare of a lettuce farmer.  Pity they don't actually show you any in the trailer.  (Giant rabbits, not lettuce farmers.  Although frankly any addition would be an improvement.)

Would this strangely empty trailer actually convince anyone to watch the film?  It shows nothing of interest except a few corpses and a scared truck driver.  And that effect with the repeating rabbit's eyes is really overdone.

There are actually some famous people in this one!  Prolific leading man Stuart Whitman, slightly less prolific leading man Rory Calhoun, Psycho shower victim Janet Leigh, and the mighty DeForest Kelly - the Star Trek actor with the most ecologically unsound name.  I have no idea how they ended up in this.  I can't imagine a horror movie featuring bunny rabbits was a popular script.

Pointless coincidence trivia:  Paul Fix, who plays the Sheriff, took the part of the medical officer in the second pilot for Star Trek.  The medical officer in the full series was, of course, 'Bones' McCoy - played by DeForest Kelly.

Favourite bit:  When the voice-over carefully pronounces 'mutant' as "mew-tant", which is how it was pronounced in cheapo sci-fi classic This Island Earth.
