Barry Levinson is attached to direct Brother Jack for Columbia Pictures, based on the life of human rights activist Jack Healey.

Kelly Masterson is doing a rewrite of Harley Peyton’s screenplay about an idealist who leaves the priesthood to wage a one-man war to raise consciousness about human rights.

Healy, who heads a Washington DC-based non-profit called the Human Rights Action Network, is producing with Mosaic.

“Barry Levinson is one of the industry’s most thoughtful, accomplished and acclaimed directors,” Doug Belgrad, who serves as president of Columbia Pictures alongside Matt Tolmach, said.

“His work chronicling the life of Dr Jack Kevorkian [in the HBO biopic You Don’t Know Jack] was brilliant and we think his take on how one social activist can influence a nation will be equally engaging and compelling.”

Belgrad and Jonathan Kadin will oversee the project for Clumbia and David Householter will do the same for Mosaic along with George Gatins. Levinson and Masterson are represented by ICM.
