Mom writer/producer Susan McMartin is adapting Patti Davis’ 2015 novel The Earth Breaks In Colors for the screen as an original movie.

Published by Huqua Press, The earth breaks in colors 2the book tells a story of race and redemption in which a racially fueled incident exposes the fissures that sit beneath the surface of friendships and families, causing even more damage than the massive earthquake that separates them. Primary Wave’s Ben Press and Brad Kaplan are producing.

McMartin penned the screenplay for Eddie Murphy starrer Mr. Church, which recently bowed at the Tribeca Film Festival. She also previously served as a writer/co-producer on Two And A Half Men.

McMartin is repped by Primary Wave Entertainment, UTA and Morris, Yorn, Barnes’ Gregg Gellman.
