The beloved children’s show is back… with a horrible, bloody vengeance.

Warner Bros. Home Entertainment and Syfy are bringing back the characters from Hanna-Barbera’s variety program “The Banana Splits Adventure Hour” for the violent, rated R The Banana Splits Movie, and we’ve got the official trailer for ya today courtesy of Syfy Wire!

Bingo, Fleegle, Drooper and Snorky will return in the original movie that’s set to “premiere this year from Blue Ribbon Content, Warner Bros Television Group’s digital studio, via a Warner Bros. Home Entertainment release that will be followed by the television debut on Syfy.”

In the upcoming horror flick, “A boy named Harley and his family (brother Austin, mother Beth, and father Mitch) attend a taping of The Banana Splits TV show, which is supposed to be a fun-filled birthday for young Harley and business as usual for Rebecca, the producer of the series. But things take an unexpected turn — and the body count quickly rises. Can Harley, his mom and their new pals safely escape?”

In the world of “mockbusters,” this is one of the most clever I’ve seen. They actually beat a Five Nights at Freddy’s movie to the punch by picking up a 60s variety show with a similar aesthetic and turning it into a horror movie. And it looks pretty good too! Find the trailer below.

The film stars Dani Kind (Wyonna Earp), Finlay Wojtak-Hissong (The Kindness of Strangers), Romeo Carere, Steve Lund (Schitt’s Creek) and Sara Canning (The Vampire Diaries).

Danishka Esterhazy (Level 16) directed from a script by Jed Elinoff & Scott Thomas.

Thirty one episodes of “The Banana Splits Adventure Hour” aired between 1968 and 1970. Sid and Marty Krofft designed the animal costumes as well as the sets for the series.
