Dr. Rottenberg, the greatest Martian scientist, comes to Planet Earth to make preparations for a wild invasion involving re-animated Earth bodies, Martian zombies and teenagers playing in the woods. Criaturas Hediondas is one of the first Brazilian Shot On Video (SOV) to have national distribution via VHS tapes that were marketed in stands at grindcore, death metal and punks shows, becoming a reference (at the time) in the national underground. The video was filmed with a VHS camera and mounted from video to video, in an analog way.

This was my first attempt at making a movie. It was unabashedly inspired by Edward D. Wood Jr.'s Plan 9 from Outer Space (1959), one of the culprits in making me want to write increasingly meaningless scripts (the other is Jesus Franco). Until the second order, the 20-minute copy of this film, which was never edited, is lost.
