As the decade drew to a close, Foster continued to mix acting with directing. She starred together with Sterling Brown in the dystopian film Hotel Artemis (2018). Although the film was a commercial and critical disappointment, Foster's performance as Nurse Jean Thomas, who runs a hospital for criminals, received positive notices. Mick LaSalle of the San Francisco Chronicle's stated that "not enough can be said about the performance of Foster in this film. She brings to the role a quality of having seen the absolute worst in people, but also the suggestion that, as a result, she accepts them on their own terms and knows how to handle any situation." Rick Bentley from Tampa Bay Times declared Foster's performance one of her "best and most memorable performances." The same year, Foster co-produced and narrated Be Natural: The Untold Story of Alice Guy-Blaché (2018), a documentary on one of the first female film directors.
