Batman vs. Teenage Mutant Ninja Turtles is an American animated superhero film directed by Jake Castorena and written by Marly Halpern-Graser.

Inspired by the DC Comics and IDW Publishing comic book miniseries Batman/Teenage Mutant Ninja Turtles by James Tynion IV and Freddie Williams II, the story focuses on Batman, Robin, and Batgirl teaming up with the Teenage Mutant Ninja Turtles in order to save Gotham City from chaos at the hands of both Shredder and Ra's al Ghul.

Animation in association with DC Entertainment and Nickelodeon, the film features the voices of Troy Baker, Eric Bauza, Darren Criss, Kyle Mooney, and Baron Vaughn.

Meanwhile, it is revealed that the four 'Metahumans' Batgirl sighted are actually the Teenage Mutant Ninja Turtles, currently tracking the Shredder's nefarious actions to Gotham City, having learned he has allied with an unknown party.

[2] In May 2019, Jake Casterona was announced to be directing from a screenplay by Marly Halpern-Graser, with Ben Jones producing; he previously worked on both Batman: The Brave and the Bold (2008–11) and Teenage Mutant Ninja Turtles (2012-17).

[3] Early during production, Jones wanted to omit the interdimensional aspect of the original comics, due to both his love for crossovers such as Superman vs. Spider-Man that established both properties as existing in the same reality, as well as simplifying the story.

[4] Due to this, Halpern-Graser sought to instead stay faithful to the comic's tone and structure while incorporating these changes to the story, with multiple lines and panels being adapted verbatim to the film.

The film features Darren Criss, Eric Bauza, Kyle Mooney and Baron Vaughn as the four Turtles: Raphael, Leonardo, Michelangelo and Donatello.

[2] Other key cast members of the film were revealed a month later, which consists of Ben Giroux as Robin, Andrew Kishino as the Shredder, Keith Ferguson as both Baxter Stockman and Two-Face, Brian George reprising his role as Alfred Pennyworth from Batman: The Killing Joke, and Jim Meskimen as both Commissioner James Gordon and the Scarecrow.

[4] According to producer Ben Jones, Nickelodeon executives mandated for none of the cast members from the then-current series Rise of the Teenage Mutant Ninja Turtles to be brought back to reprise their roles.
