AMC+ acquires 'Silent Night' starring Keira Knightley

Sept. 9 (UPI) -- AMC+ has acquired dark comedy-drama Silent Night starring Keira Knightley and will release the film in December.

Silent Night will be released into theaters and onto AMC+ in North America at the same time. AMC+ and RLJE Films, a business unit of AMC Networks, completed the acquisition.

The film, which marks the directorial debut of writer Camille Griffin who also penned the script, follows a group of friends reuniting to celebrate Christmas as the world faces impending doom.

"Burdened with the inconvenience of mankind's imminent destruction, they adopt a stiff upper lip, crack open another bottle of prosecco and continue with their festivities. But no amount of stoicism can replace the courage needed for their last night on Earth," reads the synopsis.

Co-stars include Matthew Goode, Roman Griffin Davis, Annabella Wallis, Lily-Rose Deep, Sopé Dírísú, Kirby Howell-Baptiste, Lucy Punch, Rufus Jones and Trudie Styler.

Matthew Vaughn (Kingsman), Trudie Styler (Moon) and Celine Rattray (The Kids Are Alright) serve as executive producers.
