Wonder: Owen Wilson joining Julia Roberts, Jacob Tremblay

The family in Wonder might have found its dad. Owen Wilson is in talks to join Julia Roberts and Room breakout Jacob Tremblay in the big-screen adaptation of Raquel J. Palacio’s novel, a source tells EW.

Wonder follows Auggie Pullman (Tremblay), a 10-year-old boy with a facial deformity who enrolls in a private school after years of homeschooling. If a deal closes, Wilson would star as Auggie’s father. “In a wonder of a debut, Palacio has written a crackling page-turner filled with characters you can’t help but root for,” EW wrote in its A- review of the book.

Wilson most recently starred in Zoolander 2, returned to the runway as Hansel. The actor has also been cast in a pair of comedies: one with Zach Galifianakis, Kristen Wiig, and Jason Sudeikis (Masterminds), and another alongside J.K. Simmons and Ed Helms (Bastards).

The movie, directed by The Perks of Being a Wallflower helmer and scribe Stephen Chbosky, is set for an April 7, 2017 release.

Variety first reported the news.
