A fistful of teenaged mall employees hold a drunken after-hours orgy at the end of their shift, just days after the installation of three roving anti-theft robots on the premises. In a typical bit of B-movie magic, the control suite is struck by half a dozen bolts of lightning and the automatons begin indiscriminately slaughtering everything with two legs and a pulse. Did I mention this is a Roger Corman production?

Mired in the trappings of every bad direct-to-video slasher to ever burst upon the scene in the 1980s, it's deliciously, laughably awful. Although they produce sounds on par with a blender set to puree every time they're on-screen, these bots are able to routinely sneak up on their unsuspecting prey throughout the film, slinking like cats through the night. They're far from intimidating, with bulky tank treads and tiny little T-Rex arms to spin and clap for no particular purpose, but I suppose the kids' fear of them is somewhat justified after seeing a friend's head turned to mash by a well-placed laser shot.

Crammed full of stupid decisions, silly special effects, well-glazed acting and tits, tits, tits, it's got everything you'd expect from the genre and the period... except chopping. These monsters prefer to do their killing with beams of searing pink light.

***Killer security robots at a Southern Cal mall***

Security robots at a Los Angeles mall malfunction after a lightning strike and become a deadly threat to a group of youths partying at a furniture store after hours.

“Chopping Mall” (1986) takes the malevolent robot idea of “Westworld” (1973) and places it in the mall setting of “Dawn of the Dead” (1978) with robots that look like malicious versions of “Short Circuit” (1986) and R2D2. “RoboCop” didn’t debut until the next year.

Winsome girl-next-door Kelli Maroney is a highlight as protagonist Alison while Russell Todd from “Friday the 13th Part 2” (1981) is stalwart as Rick. Suzee Slater as Leslie is a’right. This is a spirited Grade B flick but at the end of the day it’s a throwaway; it’s fun and well-executed, but somehow hollow and forgettable.

The movie runs 1 hour, 17 minutes, and was shot in Los Angeles at the Sherman Oaks Galleria, which was also used in “Fast Times at Ridgemont High” (1982) and “Terminator 2: Judgment Day” (1991).
