As the man who wrote both 2004's Saw and 2010's Insidious, Leigh Whannell has helped create two long-running horror movie franchises. But the Australian claims he had no thoughts about a possible sequel to the just-released The Invisible Man when he was making the hit Elisabeth Moss-starring film, which be both wrote and directed.

"I haven’t put any thought into a sequel," Whannell told EW before the release of the movie. "I’m a pretty superstitious filmmaker. I don’t want to jinx anything. I've been involved with movies that have had a lot of sequels, like the original Saw film obviously spawned a whole franchise, as did Insidious. But I can tell you with total honesty that in the case of both of those films I never thought about a sequel. I would never want to jinx the release of a movie by thinking about what comes next."

The likelihood of an Invisible Man sequel now seems high. The horror movie won this weekend's box office with an estimated $29 million and on Saturday it was announced that Whannell has signed a first look deal with Blumhouse, which produced the film.

In The Invisible Man, Moss plays Cecilia Kass, who is trapped in a violent, controlling relationship with a wealthy and brilliant scientist portrayed by Oliver Jackson-Cohen (The Haunting of Hill House). Cecilia escapes in the dead of night and disappears into hiding, aided by her sister (Harriet Dyer), their childhood friend (Aldis Hodge), and his teenage daughter (Storm Reid). But when Cecilia’s abusive ex dies by suicide and leaves her a generous portion of his vast fortune, she suspects his death was a hoax. As a series of eerie coincidences turn lethal, threatening the lives of those Cecilia loves, her sanity begins to unravel as she desperately tries to prove she’s being hunted by someone nobody can see.

“The interesting thing was that I was constantly shooting these empty rooms, and empty corridors, and there’s something a bit uncinematic about that,” Whannell told EW last year. “I mean, when you make a movie, the idea is that you put people in the frame — you put something in the frame. When you’re shooting nothing, it goes against the grain of every cinematic instinct you have!”
