The creator of the Xbox has shared a fascinating behind-the-scenes story about how the Jurassic Park film series actually began as a pitch for a video game.

In a Twitter thread, Seamus Blackley said in 2012 he left his job at the Creative Arts Agency to work with director Steven Spielberg on a new Jurassic Park video game. Blackley came up with a story and design elements for the game, and a trailer was produced. After a change in management at Jurassic movie studio Universal, this game became a film--Jurassic World.

Blackley said he was hoping for the game to make up for the Jurassic Park game he made in 1998, Trespasser, which he described as a poorly received "skid mark."
