The annual Cinepocalypse event returns to the Music Box Theatre in Chicago from June 13-20, and we shared this year’s lineup with you just yesterday. But there was one incredible gem buried in there that you might have missed, and it’s well deserving of a solo spotlight.

Back in 1994, one year after the release of Jurassic Park, a movie called Tammy and the T-Rex came along, the sort of so-bad-it’s-good gem that has become something of a cult classic over the years. The version of the film we’ve all seen is rated PG-13, but as it turns out, an R rated “gore cut” has just been found after all these years… and it’s screening at Cinepocalypse!

Yes, the newly-unearthed 35mm print will be screening for the *very first time* at the event.

In the Stewart Raffill-directed Tammy and the T-Rex, starring Denise Richards as Tammy and an animatronic dinosaur as, well, the T-Rex, “An evil scientist implants the brain of Michael, a murdered high school student, into an Tyrannosaurus. He escapes, wreaks vengeance on his high school tormentors and is reunited with his sweetheart Tammy.”

The late Paul Walker also starred in the sci-fi/comedy!
