Radius is following through on its promised expansion of “It Follows,” taking the horror pic into 1,200 U.S. theaters this weekend.

“It Follows” launched on Friday the 13th in four theaters and grossed an impressive $160,089 in its first weekend — the best opening in limited release for a horror film since 2010’s “Paranormal Activity” — causing Radius to pull the plug on plans for a March 27 DVD/VOD release.

It then expanded to 32 locations for its second weekend, grossing $344,874 and finishing 19th on the box office chart. The film, directed by David Robert Mitchell from his own script, has a 94% “fresh” rating on the Rotten Tomatoes site.

Maika Monroe stars as a 19-year-old who, after a seemingly innocent sexual encounter, suddenly finds herself plagued by nightmarish visions — leaving her unable to shake the sensation that someone or something is following her. Keir Gilchrist, Daniel Zovatto and Jake Weary also star.

Radius said Tuesday that “It Follows” will be available on VOD and DVD later this year after its theatrical run. Major chains such as AMC continue to strongly oppose VOD releases while a film is playing theatrically.

“It Follows,” directed by David Robert Mitchell from his own script, premiered at the Cannes Film Festival last year. Variety’s Peter Debruge said, “This stylish, suspenseful chiller should significantly broaden Mitchell’s audience without disappointing his early supporters in the slightest.”

Warner Bros. is opening Will Ferrell-Kevin Hart comedy “Get Hard” at more than 3,100 domestic locations this weekend, and DreamWorks is launching animated comedy “Home” at 3,600 sites in the U.S.
