A feature film version of Hartinger's first novel, Geography Club, was released in November 2013, co-starring Scott Bakula. The book is now being developed as a television series.[3]
Also a screenwriter, nine of Hartinger's screenplays have been optioned for film, and four are currently in various stages of production, including The Starfish Scream, a gay teen drama; Decked, the animated “true” story behind a deck of playing cards; and Project Sweet Life, a teen caper movie (based on his own novel) currently in production for a 2020 release.[4]
Hartinger's writing honors include The Lambda Literary Award; a GLAAD Media Award; the Scandiuzzi Children's Book Award; and an Edgar Award nomination. Screenwriting awards include the Screenwriting in the Sun Award, a Writers Network Fellowship, and first place in the StoryPros, Fresh Voices, Acclaim, and L.A.

In 1990, Hartinger co-founded one of the world's first LGBT youth support groups, in his hometown of Tacoma, Washington.[7]
