Sam Asghari, Britney Spears' fiancé, joins cast of 'Hot Seat' alongside Mel Gibson

Sam Asghari and Kevin Dillon are officially in the "Hot Seat," according to an exclusive report from Deadline's Justin Kroll.

Asghari, Britney Spears' 27-year-old fiancé, has previously secured guest roles on "NCIS," "Hacks" and "Black Monday," while Dillon is known for his Emmy-nominated work as Johnny "Drama" Chase on "Entourage."

Mel Gibson was attached to star in the project earlier this month.

Kroll provided more information on the forthcoming action thriller:

"The Lionsgate company Grindstone Entertainment will handle North America distribution, and Highland Film Group is repping foreign sales. James Cullen Bressack will direct. He just helmed Fortress with Chad Michael Murray and Bruce Willis, which is in post.

"In Hot Seat, an ex-hacker is forced to break into high-level banking institutions by an anonymous man who planted a bomb under his chair at his office. Gibson plays the man who must try to penetrate the booby-trapped building to get a man (Dillon) off the hot seat."

Asghari and Spears announced their engagement Sept. 12. They first met while filming Spears' "Slumber Party" music video in late 2016.
