Arrested Development star Michael Cera and The Hangover’s Zach Galifianakis have signed on to co-star in the upcoming LEGO Movie spinoff LEGO Batman.

Update (August 12): Zach Galifianakis has joined LEGO Batman as The Joker, THR reports. This cast gets more impressive with each new actor who joins!

Original Story (July 16): Cera is a comedic actor who was up for another WB project, J.K. Rowling’s Fantastic Beasts, earlier this summer. It looks like the studio was eager to get him involved in a project one way or the other!

LEGO Batman will star Will Arnett voicing the caped crusader, as he did in the 2014 runaway hit The LEGO Movie directed by Chris Miller and Phil Lord.

After the success of The LEGO Movie ($257 million domestically, $211 internationally), Warner Bros. announced that they were developing several other LEGO-based projects:

  1. A sequel to the original
  2. The aforementioned Batman spinoff
  3. A second spinoff themed around Ninjago
  4. A third spinoff tentatively titled Billion Brick Race by Jason Segel and Drew Pearce

Get ready for a lot of LEGO!

LEGO Batman is due to hit theaters in 2017.
