Discover the work

David O'Leary Founder · WGAw Member

I didn't choose storytelling.
It chose me.

It's been a wondrous journey so far.

I'm a film and TV writer-producer, creator, showrunner, and story consultant whose work extends to audio, branded entertainment, and emerging platforms. Most recently, I sold my original sci-fi crime series The Dark Files to Netflix on pitch, and staffed as Consulting Producer on NBC's Law & Order: Organized Crime. I've sold projects to TNT, Miramax, A+E Studios, Universal TV, and others.

I'm best known for creating and executive producing Project Blue Book for HISTORY — a UFO drama that aired in 165 countries, topped the cable charts in 2018–19, landed on the New York Times Arts Section cover, and brought Robert Zemeckis on board as EP. I began my career in creative development at Warner Bros., Focus Features, Valhalla, and others, and have been on both sides of the table ever since.

For 17 years I've taught at New York Film Academy and guest lectured at USC, Pepperdine, and AFI. The craft is always the same: find the story, shape it, and make it matter. I founded Omen Entertainment on a belief I've carried since interning at New Line Cinema — the best stories are never accidents. They're the ones you recognize when you finally learn to pay attention.
