The Dark Tower,” Sony’s upcoming adaptation of Stephen King’s fantasy series, is moving its release to give the film more time to finish its visual effects work, Variety has confirmed.

The picture, which stars Idris Elba and Matthew McConaughey, was originally scheduled to debut on Feb. 17, 2017, when it would have faced off against the horror film “A Cure for Wellness,” the Ice Cube comedy “Fist Fight,” and action epic “The Great Wall,” as well as the second weekend of “Fifty Shades Darker.” A new date hasn’t been determined, but sources say it will likely bow in July, putting it in the middle of summer blockbuster season.

Sony is said to be pleased with the early footage, and believes that the picture could spawn a new film franchise. “The Dark Tower” has an intricate mythology. The film is set in an apocalyptic world and follows a wandering warrior (Elba) as he journeys to a tower that stands at the nexus between space and time. Hollywood has tried for years to adapt the books. At one point, Ron Howard was slated to direct Javier Bardem for Universal, but the project collapsed over budget concerns.

Shooting wrapped on “The Dark Tower” last summer and the new release date will enable the film to have more time to complete its post-production work. MRC and Imagine Entertainment partnered on the film with Sony.

Entertainment Weekly first reported the date shift.
