CULVER CITY, Calif. — Back when there were only a couple of “Harry Potter” pictures, and provocative youth films like “The Hunger Games” and “Twilight” were barely a twinkle in Hollywood’s eye, Warner Brothers tried — and failed — to make a movie of Orson Scott Card’s book “Ender’s Game.”

Now, Gigi Pritzker, an heiress who produces movies, is poised to expand her company atop the one that got away from Warner.

The film version of “Ender’s Game” is set for release on Nov. 1 by Lionsgate’s Summit Entertainment unit. A tale of violent interplanetary warfare, it is intended to extend the young adult line of those recently merged studios, whose blockbusters, “The Hunger Games” and the “Twilight” films, have had about $4 billion in worldwide ticket sales.

But “Ender’s Game” was actually built by Ms. Pritzker’s OddLot Entertainment.

OddLot, founded in 2005, is tiny, with only about a dozen employees who operate from warehouse-style space near the Sony Pictures studio here. It picked up the pieces when Warner’s rights to Mr. Card’s book expired, and four years ago, it began assembling its most expensive movie to date, with a production budget of more than $110 million.
