When Ryan Green, a video game programmer, learns that his young son Joel has cancer, he and his wife begin documenting their emotional journey in the form of an unusually beautiful and poetic video game. THANK YOU FOR PLAYING follows Ryan and his family over two years through the creation of “That Dragon, Cancer” as it evolves from a cathartic exercise into a critically acclaimed work of art that sets the gaming industry abuzz. Nominated for Best Documentary at the Tribeca Film Festival. "A documentary that works as both an emotional portrait of a slow-motion family tragedy and a slippery inquiry into the therapeutic properties of making art." - Justin Chang, Variety
