‘Shazam’ actor Zachary Levi has been cast in the lead for the family drama ‘The Unbreakable Boy’ at Lionsgate.

Levi will play the Father of Austin, a boy with both rare brittle-bone disease and autism. But what makes Austin truly unique is his joyous, funny, life-affirming worldview that transforms and unites everyone around him. Levi’s character changes his life as he comes to see Austin not as the symbol of something broken, but the triumph of an indestructible spirit.

Based on the book by Scott M. LeRette, Jon Gunn will take the helm on the film in which he co-wrote the screenplay with Susy Flory.

Jon Erwin and Andrew Erwin alongside Kevin Downes will produce through their Kingdom Story Company banner. Jerilyn Esquibel and Peter Facinelli will also produce.

Production is due to commence imminently. Once production has finished on this project, Levi will go straight into working with the Erwin brothers yet again on ‘American Underdog: The Kurt Warner Story,’ which will begin production next year for Kingdom Story and Lionsgate. He will also be reprising his role in ‘Shazam: Fury of the Gods’.
