The duo have been tapped to star alongside Mark Wahlberg in the suspense thriller that is being directed by Mel Gibson.

In the movie, Wahlberg portrays a pilot transporting an Air Marshal (Dockery), who has been tasked with accompanying a fugitive (Grace) to trial. As they cross the Alaskan wilderness, tensions rise and trust is put to the test as not everybody is who they seem.

The flick is Mel's first time behind the camera since the Oscar-nominated 2016 war drama 'Hacksaw Ridge' and marks a reunion for him and Wahlberg after they starred together in 'Father Stu' and collaborated on the 'Daddy's Home' series.

Lionsgate movie chairman Joe Drake said when the project was announced last year: "We love the undeniable electric pairing of Mel Gibson and Mark Wahlberg.

"These world-class talents combining for this dynamic, character-driven film will make 'Flight Risk' one of the most suspense-filled, must-see events of the year."

Gibson has directed five movies – including 'Braveheart' – over the past 30 years with each one proving successful at the box office.

Meanwhile, Michelle previously confessed that doesn't have a career strategy and is motivated by good "writing and the character" when selecting projects to work on.

The 42-year-old actress told Collider: "I don't tend to be strategic, in a way that's like, 'Okay, I need to do this now because I just did X, Y and Z before.' It really comes down to the writing and the character.

"Often, it's whether I feel something, in my gut, for the character."
