Actor Natacha Karam, popularly known for 911: Lone Star, is set to act with veteran action star Sylvester Stallone in Samaritan.

Reports say the superhero-based adventure drama from MGM will be directed by Overlord director Julius Avery.

Set 20 years after an epic battle that left a city's villain and hero missing or worse, the film will chronicle the story of a boy who tries to find the hero.

Stallone, 73, will essay the role of Stanley Kominski, a sanitation worker trying to live a normal life while harbouring a deep secret. Karam, 26, will play a dangerous and unpredictable henchperson to the story's antagonist, played by Game of Thrones actor Johan 'Pilou' Asbake. Samaritan will also feature Javon Walton and Martin Starr.
