My review was written in July 1989 after watching the movie on TWE video cassette.
"Deadly Weapon" is a failed attempt at a high-concept picture from Charles Band's late fantasy factory, Empire PIctures. Story of a bullied youngster who goes high-tech for revenge went unreleased, inherited, as a video, by TWE.
Debuting helmer Michael Miner exhibits technical skill but does not establish a consistent tone for this mishmash. Rodney Eastman is Zeke, a 15-year-old in the small town of King Bee, Arizona, who thinks he's a visitor from Outer Space, waiting for the Mother Ship to come for him. He finds an anti-matter pistol belonging to the army, lost in a train wreck nearby.
Zeke proceeds to blast his enemies (including his mean daddy) with the formidable revolver and comically rounds up the town preacher, sheriff and mayor, locking them up in the car trunk as he goes joyriding in the thrill-seeking Kim Walker's pink Cadillac convertible.
While the army mobilizes to carefully put Zeke out of commission (the gun's power source can explode like a 200-kiloton bomb), pic turns maudlin en route to a tragic finish.
Eastman displays convincing angst in the central role, with Walker, a beautiful blonde who was one of the "Heathers" in the recent New World release, making a solid impression in an underwritten part. Special effects and other the credits are fine.
