Jack Whitehall has signed on to voice Kenzie in 20th Century Fox's Mouse Guard adaptation, according to The Hollywood Reporter.
Whitehall voiced Gothi the Troll in Walt Disney Animation's Frozen, and recently appeared in Disney's Nutcracker and the Four Realms.
Based on the BOOM! Studios/Archaia Press comic book series by writer/artist David Petersen, Fox's Mouse Guard is directed by Wes Ball. Previous reports indicate that Idris Elba, Andy Serkis, Thomas Brodie-Sangster, and Samson Kayo have already signed on for the film.
Mouse Guard is a motion capture animated film, and is expected to begin production in May.
