February next year will mark the ninth solo Batman film. But, as you can imagine after Phil Lord and Chris Miller's The LEGO Movie (2014), this incarnation will have its tongue placed very firmly in its cheek. But hardcore DC Comic fans shouldn't fret – McKay's film doesn’t mess too much with the caped crusader's formula, making sure Alfred (Ralph Fiennes), Robin (Michael Cera) and The Joker (Zach Galifianakis) are still very much in the frame.
"Ralph committed fully to LEGO Alfred," McKay told Empire. "He told me he was inspired by Ruggles Of Red Gap (1935). It was amazing seeing him in the booth doing all this space work." And what of Galifianakis' Joker, the second (after Suicide Squad's Jared Leto) in as many years? "I wish I had a story about Zach sending us dead rats," laments McKay, "but he's an incredible Joker. I've listened to him riff with Will for hours".
There is also a new spin on the Boy Wonder. "Bruce accidentally adopts him at a party," the director tells us of the movie's main duo. "Robin is a Book Of Mormon-esque character, the ray of light to Batman's brooding, Lord Byronic hero. It's their dynamic that carries the movie, these polar opposites going head to head."
The LEGO Batman Movie swoops into cinemas on 10 February, 2017.
