In 2017, a 35mm print of an alternate, pre-censorship cut of the film was discovered, under the title Tanny and the Teenage T-Rex. This version features the long-rumored scenes of gore and extreme violence that were sloppily edited from the film in order to attain a PG-13 rating. Scenes include various moments of excessive bloodshed and a graphic brain transplant, as well as a great deal more profanity. In total it runs six minutes longer than the cut that appeared on VHS in 1994. Vinegar Syndrome scanned and restored the film at 4K resolution, and gave it a limited theatrical re-release, and Blu-Ray/Ultra HD release in the fall of 2019.
