FilmBuff has licensed worldwide rights to distribute Thank You For Playing, the Tribeca Film Festival documentary from David Osit and Malika Zouhali-Worrall that follows indie video game developer Ryan Green as he created That Dragon, Cancer, a game based on his youngest son’s battle with terminal cancer. The game was released this month, and FilmBuff plans a platform release of the docu on March 18 followed by VOD.

“This is an emotionally complex and artistically important documentary, and we’re thrilled to be bringing it to the audience that it deserves,” said FilmBuff’s Sam Scupp. “The human story behind the game is even more powerful through the lens of the parents and family who live through it.”

Osit and Zouhali-Worrall have launched a Kickstarter campaign aiming to raise $35,000 for a grassroots tour to bring the film to theaters and free screenings at community centers, places of worship and college campuses.
