I noticed we haven't got a thread for this yet. Benedict will voice the character of Lewis in this animated feature film. Currently in post-production, the expected release date is 25 December 2016. Hopefully there will be more news about this in the coming months.
Magik is the story of Lewis Clark, a brilliant author who stumbles upon a world of Magik after the disappearance of his two young children. He begins a quest to try to stop the insidious evil that threatens to destroy both his world (London at the time of the Blitz) and the parallel Magik one.
Voice cast also includes Matthew Goode, Benedict 's costar from The Imitation Game. Check out the IMDB page http://www.imdb.com/title/tt1713496/
