The Lego Batman Movie is a 2017 computer-animated superhero comedy film produced by Warner Animation Group, DC Entertainment, RatPac Entertainment, Lego System A/S, Dan Lin's Lin Pictures, Phil Lord and Christopher Miller's Lord Miller Productions, Roy Lee's Vertigo Entertainment and Animal Logic, and distributed by Warner Bros. Pictures. It was directed by Chris McKay in his directorial debut, from a screenplay by Seth Grahame-Smith, Chris McKenna, Erik Sommers, Jared Stern, and John Whittington, and produced by Dan Lin, Roy Lee, and Phil Lord and Christopher Miller. Based on the characters from the DC Universe created by DC Comics and the Lego DC Super Heroes' Batman toy line, the film is a collaboration between production houses from the United States, Australia, and Denmark, the first spin-off in The Lego Movie film series and the second installment overall. The story follows the title character as he attempts to overcome his greatest fear to stop the Joker's latest plan. The film features Will Arnett reprising his role as Batman from The Lego Movie alongside Zach Galifianakis, Michael Cera, Rosario Dawson, and Ralph Fiennes.
Development of The Lego Batman Movie started in October 2014, after Warner Bros. announced several Lego films, following the critical and commercial success of The Lego Movie, while Chris McKay was hired to direct the film after being replaced by Rob Schrab to direct the sequel to The Lego Movie. The film pays homage for numerous references to previous Batman films, cartoons and comics. Like The Lego Movie, the animation was provided by Animal Logic.
The Lego Batman Movie had its world premiere in Dublin, Ireland on January 29, 2017, and was released in the United States on February 10, 2017. This was the first Lego Movie to be released in RealD 3D, Dolby Cinema, IMAX, IMAX 3D and 4DX. The film received generally positive reviews from critics for its animation, voice acting, soundtrack, visual style, and humor, and was also commercially successful, having grossed $310 million worldwide against a budget of around $80 million.
A sequel, Lego Superfriends, was announced in 2018, but was cancelled after Universal Pictures acquired the Lego franchise rights.
