The Survivalist is a 2021 American action thriller film directed by Jon Keeyes and written by Matthew Rogers starring Jonathan Rhys Meyers and John Malkovich.

Aaron seeks Sarah because she is supposed to be immune to the virus and could thus hold the key to a potential cure.

Escaping a refugee camp in Pennsylvania where 20,000 people died of the virus with her brother, who sacrifices himself to protect her, Sarah makes her way to the home of Ben Grant, a former FBI cartographer turned survivalist following the murder of his father.

After Sarah's presence infected the refugee camp, the doctors had lied about her immunity rather than admitting to their mistake.

Leslie Felperin of The Guardian awarded the film two stars out of five and wrote, "The palette of sludge and gravel doesn’t help and the performances represent no one’s best here, although it’s nice to see Rhys Meyers back in action after some decidedly low-profile movie roles.
