It was released just in time to coincide with the release of another Blumhouse film, Halloween Kills.
The trailer plays on the creep factor while also evoking memories of Andy Muschietti's original It movie.
On April 26, six months after the original trailer's release (though the film's postponement until June is likely the cause), a second trailer for the film was released online, just before the film was shown to exhibitors at this year's CinemaCon.
The trailer doesn't necessarily provide us any new information, but it does give us a good idea of what to expect.
It does feature a few blurbs from critics complimenting Ethan Hawke's erratic performance as well as the fact that the picture is very disturbing.
The abduction tale of The Black Phone is turned on its head. The film is set in the 1970s in the suburbs of Colorado, where a serial murderer known as The Grabber is hunting down children.
