Comic-Con 2016: Will Arnett teases LEGO Batman

The LEGO Batman Movie may be all about the adventures of Batman and Robin, but it’ll also be a bit of a Bluth family reunion. Will Arnett will soon be suiting up as the Caped Crusader, with Michael Cera as his sidekick-in-spandex.

Arnett stopped by EW’s studio at San Diego Comic-Con — with LEGO Batman himself, in all his miniature plastic glory — to talk about how excited he was to reunite with his former on-screen nephew.

“When they said they wanted Michael to play Robin, I was like, ‘Yeah, that’s the best idea ever,’” Arnett said. “So I got in touch with Michael and was like, ‘Dude, you have to do this, this is going to be super fun.’ And from moment one, he was like, ‘Yes, I’m in,’ which was great. And he’s done an awesome job, of course. He’s such a hilarious, talented guy. And it’s kind of cool to have those worlds collide.”

But Arnett also cautioned that LEGO Batman and Robin don’t exactly have a familial relationship yet.

“It’s early in their time together,” he added. “There are some growing pains. Batman, as we all know of course, historically works alone. So when he’s got this new person, or sidekick if you will, it’s a tough adjustment for Batman.”

No word yet on whether Batman will be swapping his Batmobile for a LEGO version of the Bluth family stair car.

The LEGO Batman Movie will hit theaters on Feb. 10, 2017.
