Momentum Pictures has acquired worldwide distribution rights to bullying drama “Milton’s Secret,” starring Michelle Rodriguez, Donald Sutherland and William Ainscough.

The movie, currently in post-production, is based on the 2008 children’s book “Milton’s Secret: An Adventure of Discovery Through Then, When, and the Power of Now” by Eckhart Tolle and Robert S. Friedman. Ainscough plays an eight-year-old who’s bullied at school with Rodriguez as his teacher trying to lift his spirits while his grandfather (Sutherland) shows him the secret to finding true happiness.

Buck Productions and Hulo Films are the production companies. Producers are Sean Buckley for Buck Productions, Fred Fuchs for Riverside Entertainment, as well as Stephen Huszar and Ryan Lockwood for Hulo Films.

Barnet Bain directed from a script he wrote with Donald Martin and Sara B Cooper. David Sutcliffe, Mia Kirshner, Sheila McCarthy and Hays Wellford also star.

“I am thrilled with the way the script has grown from the original foundation of the book to the screenplay, and hope this film has the power to contribute to the awakening of consciousness on our planet,” Tolle said.

Entertainment One rebooted Momentum this fall, when it struck a distribution deal with Orion Releasing. It bought Lance Armstrong biopic “The Program” at the Toronto Film Festival and Sarah Jessica Parker’s comedy “All Roads Lead to Rome” during the American Film Market.

The deal for “Milton’s Secret” was negotiated by Larry Greenberg for Momentum Pictures and Buckley on behalf of Buck Productions.
