At CinemaCon on Monday night, Sony shared a first glimpse at the highly anticipated Stephen King adaptation.

The Dark Tower type Movie

Sony debuted the first footage from its adaptation of Stephen King’s The Dark Tower at CinemaCon on Monday night, teasing the July release for the first time.

Directed by Nikolaj Arcel, who also worked on the screenplay with writers Akiva Goldsman, Anders Thomas Jensen, and Jeff Pinkner, The Dark Tower stars Idris Elba as Roland the Gunslinger and Matthew McConaughey as the villainous Man in Black.

The Dark Tower was originally set to arrive in theaters on Feb. 17 of this year. But late last year, Sony pushed the date to July 28 with an eye toward allowing Arcel and his team more time to finish the $60 million-budgeted feature’s post-production effects work. “It’s a very fiscally responsible budget, and trying to stay in budget to make money and stay profitable means the VFX won’t be finished in time [for February],” a source, speaking on condition of anonymity, told EW last year when the release delay was announced. “Now that there’s more time, they’re not paying rush charges to get the effects where they need to be.”

According to reporters in attendance at CinemaCon on Monday night, some of the effects were still unfinished in the trailer tease that Sony debuted. But it’s expected a full trailer for The Dark Tower will arrive soon.

Read on for reactions to the footage.

Earlier this month, the film’s first poster debuted online.

The Dark Tower is out July 28.
