Described[2] as a gritty and dark take on superhero movies, the story was previously adapted[a] into the Mythos Comics graphic novels by Schut, Marc Olivent, and Renzo Podesta.

The film stars Sylvester Stallone in the main role, Javon "Wanna" Walton, Pilou Asbæk, Dascha Polanco, and Moisés Arias.

Twenty five years later, thirteen-year-old Sam Cleary tries his best to help his mother with their financial crisis, and, after being threatened with eviction, he accepts a job from a gang headed by Reza.

Joe is badly injured but heals before Sam's eyes, overheating so much, he has to be cooled down by taking a cold shower and eating ice cream.

When Joe saves a young girl from an explosion caused by the gang, the media claims that Samaritan is back, threatening Cyrus' plans.

It is shown in a flashback that Samaritan had effectively won the fight but refused to kill Nemesis, instead tossing the hammer away, still viewing him as his brother.

Despite his best efforts and a change of heart, Nemesis was unable to save his brother, instead tossing both of their masks into the same fire that Samaritan fell into.

Destroying the hammer, Joe kills Cyrus by knocking him into a burning abyss - the same way Samaritan died - but almost overheats from his healing abilities and the spreading fire.

In February 2019, it was announced that MGM had acquired a spec script by Bragi F. Schut titled Samaritan to be co-produced with Balboa Productions.

[3] Schut had written the screenplay prior to adapting the story in a series of graphic novels published by Mythos Comics.

In February 2020, Martin Starr, Moisés Arias, Dascha Polanco, Pilou Asbæk, Javon 'Wanna' Walton, Jared Odrick, and Michael Aaron Milligan joined the cast in supporting roles.
