Chris Messina, Esai Morales, Michael Pena, and Gigi Zumbado have joined the cast of director Will Bridges' psychological thriller Tumor. The quartet joins the film's lead actors Sam Rockwell and Maisy Stella.

The film stars Rockwell as a private investigator in Los Angeles who looks into the disappearance of a wealthy businessperson's (Morales) daughter (Stella). However, what makes the case challenging for him is the fact that he is battling brain tumor symptoms, making his control over reality more and more precarious.

The film's makers are yet to reveal further details about the characters of Messina, Zumbado, and Pena. It brings Bridges back to direction after 2024's romance film All of You, featuring actors Brett Goldstein, Imogen Poots, Zawe Ashton, Steven Cree, and Jenna Coleman.
