The 79-year-old actor will lend his voice to the iconic supervillain Two-Face in the animated comedy spin-off of the traditional comic book movie, alongside Will Arnett who voices the caped crusader himself.

Director Chris McKay confirmed the news via Twitter when he was asked if Billy would be voicing the role, as he simply replied: "He does."

The news comes after the actor previously portrayed Harvey Dent - who later becomes Two-Face when a mob boss throws acidic chemicals at him and severely scars the left side of his face - in the 1989 movie 'Batman', but never got the chance to step into the shoes of the character's evil alter-ego.

Despite Billy saying he desperately wanted to portray the villain - which he says was the main reason he'd signed up to play Harvey Dent in the first place - the franchise moved in another direction when Joel Schumacher took over as director.

The villain would eventually be featured in 1995's 'Batman Forever', but was instead portrayed by Tommy Lee Jones.

Meanwhile, Billy Dee Williams instead became a household name for his portrayal of Lando Calrissian in the early 'Star Wars' movies.

'The Lego Batman Movie' also features the likes of Zach Galifianakis as The Joker, Michael Cera as Batman's sidekick Robin, Rosario Dawson as Batgirl, Ralph Fiennes as the butler Alfred Pennyworth, and Jenny Slate as Harley Quinn.

Singing legend Mariah Carey will also lend her voice to the animated movie, as she plays Mayor McCaskill.

'The Lego Batman Movie' is slated for release on February 10 2017.
