As it turns out, he's NOT playing The Predator - although he'd probably make for an excellent head-hunting space hunter.
Instead, child actor du jour Jacob Tremblay is set to star as the son of Boyd Holbrook's character, who has been described in THR's report as "an ex-Marine who discovers the existence of fierce aliens but finds that no one believes they exist."
The casting for Shane Black's follow-up in the series has definitely been interesting, to say the least. Keegan-Michael Key, Olivia Munn, the aforementioned Boyd Holbrook, and Thomas Jane have all announced in undisclosed roles, with consistent rumours going around that Arnold Schwarzenegger may or may not be making a cameo as Dutch.
As it stands, The Predator is headed for a 2018 release and production is due to kick off this month.
