When Ryan Green, a video game programmer, learns that his young son Joel has cancer, he and his wife begin documenting their emotional journey with a poetic video game. Thank You for Playing follows Ryan and his family over two years creating "That Dragon, Cancer," which evolves from a cathartic exercise into a critically acclaimed work of art that sets the gaming industry abuzz. Lauded as "unimaginably intimate" by The New Yorker, the film is a testament to the resilience of the human spirit and the unique ways that art and technology can help us share profound experiences. A co-production of American Documentary | POV and ITVS. Official Selection of the 2015 Tribeca Film Festival.
