The Flight Attendant herself Kaley Cuoco will be joined by Billy Bob Thornton in the high-concept thriller Role Play, it's been confirmed.

We've waited a whole year for an update on this movie, but Deadline has now provided the goods – revealing David Oyelowo (The Girl Before) is playing Cuoco's onscreen husband, while Thornton may have nabbed a key role.

Role Play upends a married couple's tranquility when their pasts catch up to them, with production scheduled to kick off in Berlin next month. It's thought Thornton's character will be "mysterious" and will have some kind of interaction with the couple.

An acting great himself, Thornton is mixing with the cream of the crop right now – turning up as Donald Fitzroy in The Gray Man for Netflix very soon.

The Gray Man co-director Joe Russo teased how this is planned as the beginning of a new spy franchise, commenting while in attendance at last year's CCXP Worlds panel: "This is being conceived as a series of films, and again, potentially branching out, we could follow other characters, but we're not gonna answer every question in the movie.

"So you're gonna finish the movie [and] have a complete story, but you're still gonna have questions about the wider universe."

Captain America's Chris Evans will breathe life into a "unique" villain on the hunt for Ryan Gosling's master assassin Court Gentry.

"He's a really unique character, and this is Evans as a villain so it's a really interesting character and I think he's going to get to flex quite a bit in this role," said Joe and his directing sibling Anthony.

The Gray Man hits UK cinemas on July 15, before streaming on Netflix from July 22.
