Michael Cera for Lego Batman

Michael Cera will voice Robin in 'Lego Batman'.
The 'Juno' star has signed on to appear as Batman's partner-in-crime in the animated film, which is Warner Bros.' spin-off of 2014's critical and commercial smash, 'The Lego Movie'.
The 27-year-old actor's 'Arrested Development' co-star Will Arnett will voice Batman, with many other people from the team behind the first film returning for the production.
Safekeepers for the Lego screen brand Dan Lin, Phil Lord, Roy Lee and Christopher Miller will produce the film while 'The Lego Movie's animation supervisor Chris McKay has been brought on board to direct.
Skilled writer Seth Grahame-Smith has also penned the script for the movie, having recently been announced as the screenwriter for the much-anticipated 'Beetlejuice 2'.
Meanwhile, Michael - who is known for his roles in 'Superbad', 'Scott Pilgrim vs. the World' and 'Nick and Norah's Infinite Playlist' - is also currently working on Seth Rogen's star-studded animated ensemble 'Sausage Party' alongside Paul Rudd, James Franco and Salma Hayek, due to be release next August.
Elsewhere, he has personally acquired the film rights to Charles Portis' 1985 novel 'Masters of Atlantis', following a man who becomes embroiled in a quasi-religious cult, which he aims to write, star in and direct.
