The film is a collaboration between production houses from the United States, Australia, and Denmark, the first spin-off in The Lego Movie franchise and the second installment overall.

The film features Will Arnett reprising his role as Batman from The Lego Movie alongside Zach Galifianakis, Michael Cera, Rosario Dawson and Ralph Fiennes.

The story follows Batman as he attempts to overcome his greatest fear while saving Gotham City from the Joker's latest scheme.

The Lego Batman Movie had its world premiere in Dublin, Ireland on January 29, 2017, and was released by Warner Bros. Pictures in U.S. theaters on February 10.

The following day, Batman's alter ego Bruce Wayne attends the city's winter gala, which is celebrating both the retirement of Police Commissioner Gordon and the ascension of his daughter, Barbara, to replace him.

Wayne is smitten by Barbara and this distraction results in him unwittingly agreeing to adopt the enthusiastic orphan Dick Grayson.

Batman and Robin recover the projector from the Atomic Cauldron of the Fortress of Solitude, break into Arkham Asylum and successfully send the Joker to the Phantom Zone.

Although his teammates achieve some success in fighting the multiverse's villains, Batman forcibly sends them away and confronts the Joker alone, fearing that he might lose them just like his parents.

Believing that Batman is incapable of changing his ways, the Joker sends him to the Phantom Zone before stealing the Batcave's stash of confiscated bombs to destroy Gotham.

Batman makes a deal with Phyllis to temporarily return to Gotham to retrieve the Zone's escaped prisoners, and arrives in time to save his teammates, apologizing to them for leaving them and requesting their help to stop the Joker.

In the aftermath, Batman reveals to Dick that he is Wayne in disguise, then goes to return to the Phantom Zone to face the consequences of his earlier behavior.

His proposal to combine all the Batman eras featured in the comic book series and various media formats, including movies and comic series, despite a couple of issues—the total inconsistency inherent to such a task, and Lego rejecting some of the characters he proposed to include in the film—was based on his desire of how to portray Robin within the film's setting.
