Justin Geldzahler is a writer and filmmaker based in the United States (of America).

He wrote, directed, and produced his first feature film Glue Trap, a dark comedy thriller available to watch on Amazon, Tubi, and elsewhere. He was also a consultant and contributing writer on the final season of HBO’s Succession.

Represented by Untitled Entertainment, Justin has developed projects with Republic Pictures, Modern Magic, TeaTime Pictures, WatchThisReady, and many other good looking people. His big sexy western The Quiet Kind was chosen for the GLAAD List and the Black List feature lab. He developed his animated series Bears In Human Suits with the Almanack Screenwriters lab in Costa Rica. And his new short film ...Oh, an erotic thriller for one, is playing on the festival circuit.

(Plus one time Justin wrote an allegedly mean tweet that Larry King was forced to read on Kimmel.)

He focuses on genre stories that double as dramedies about people struggling to connect. In addition to making tons of short films, he has researched for and contributed to Euphoria(HBO), Fosse/Verdon (FX), The Plot Against America (HBO), Respect (MGM), Outlander (Starz), and Fiddler on the Roof (MGM).
