According to AFP, Shane Black's Predator sequel/reboot will begin filming this October, with a scheduled release date of March 2018.
In an interview with AFP, Black has described the film as "...significantly bigger" than the previous films.
“To the best of my knowledge, the train is rolling. It took some convincing because they’ve been putting out these movies all along with a $50-60 million budget, and they all had a guaranteed return. But there was never the sense that it was an event picture. It was more like ‘I understand another Predator is coming out — maybe we’ll see it maybe we won’t.’”
In the past, Black has already stated that they are working on persuading star of the original, Arnold Schwarzenegger.
