After production troubles, the television part of the adaptation of Stephen King's “Dark Tower” series will now run on HBO, says producer Brian Grazer.

The "Dark Tower" series – which King has called his "magnum opus" – is a work that combines multiple genres, including fantasy, science fantasy, horror, and western. The adaptation was envisioned as both a television series and three movies. Grazer said it’s still unknown what movie studio will produce the films, which were dropped by Universal Studios in July due to budget concerns.

“We're going to do [the TV series] with HBO,” Grazer told MTV News. "We'll do the TV with HBO, and we'll do the movie with... to be determined. We'll do it right.”

Grazer said the budget has been cut back and that the movies will still be true to King’s vision.

“We've lost $45 million out of the budget,” Grazer said. "When people say no to you enough, then you have to lose money, which we've done without harming the scope of the film.”

Grazer, who’s been working with Ron Howard on the project, said he’s confident Javier Bardem will still be taking on the role of Roland Deschain, the gunslinging main character.

HBO hasn’t yet commented on the announcement.

The "Dark Tower" series consists of seven novels by King and a series of prequel comic books.
