On February 2, 2016, Warner Brothers will release a double feature, including Scooby-Doo! Wrestlemania Mystery and The Flintstones and WWE: Stone Age Smackdown.
Here are the descriptions from Amazon:
Scooby-Doo! Wrestlemania Mystery: When Shaggy and Scooby win tickets to WrestleMania, the entire gang travels in the Mystery Machine to WWE City to attend the epic event. However, when a mysterious ghostly bear appears and threatens to ruin the show, Scooby, Shaggy, Velma, Daphne and Fred work with WWE Superstars to solve the case.
The Flintstones and WWE: Stone Age Smackdown: Get ready for some raw-kin' action in this all-new, original movie that brings some of WWE's toughest, wildest superstars to Bedrock! When Fred loses his family's vacation money, he hatches one of his hair brained plans to get it back. It's a sports entertainment spectacle that involves throwing his best bud, Barney into the wrestling ring with the likes of John Cenastone (John Cena), Rey Mysteriopal (Rey Mysterio) and even The Undertaker, with Fred himself as event promoter! The crowds roar, the "clams" are pouring in from ticket sales and even Mr. McMagma (Vince McMahon) is taking notice of all the hoopla. Can Fred keep serving up bigger and badder matches or is he in for the rocky ride of his life? Including all-star appearances from The Boulder Twins (Brie and Nikki Bella) Marble Henry (Mark Henry) and Daniel Bry-Rock (Daniel Bryan), it's time to get the whole family together for a collection of hard-hitting, side-splitting laughs from the most epic event in all of prehistory!
Special features will be the same as they were on the individual movie DVDs.
