Teenage Mutant Ninja Turtles: Mutant Mayhem, the upcoming CGI animated film starring the Heroes in a Half Shell that is set to release in theaters on August 4, 2023, has received its first teaser trailer.

The teaser gives us our first look at the new iteration of the beloved TMNT brothers and many other members of the expansive cast of characters from the franchise. The new animated TMNT film is set to provide an all-new telling of the story of the brothers coming out of the sewers for the first time and becoming the heroes that we know them as today.

The new TMNT film will be the second CG film outing for the Turtles after 2007's TMNT and the first time the Turtles will be on the big screen since Bay's 2016 film Teenage Mutant Ninja Turtles: Out of the Shadows. Mutant Mayhem started life as the third entry in Bay's live-action TMNT series before it was picked up in 2018 by Seth Rogen, who serves as a producer on the film, and his Point Grey Pictures production company, at which point it was decided that the film will be an animated film instead of following the look of Bay's previous films. Rogen previously told Collider that he wanted to use this iteration of the turtles to focus on the teenage part of TMNT, showing how Michelangelo, Donatello, Raphael, and Leonardo come into their own.
