Set in an alternate reality where hitmen for hire infiltrate the brains of innocent people to enact their violent crimes, Possessor is a sci-fi thriller done right. Director Brandon Cronenberg has no problems filling the very big, and very bloody, shoes of his cult icon father David (The Fly, Dead Ringers) in this visionary indie film. Relying heavily on the phenomenal performances from Andrea Riseborough and Christopher Abbott, Possessor is one film that will be hard to shake. One might even say it’ll burrow in your brain like a parasite.

Elite assassin and family woman Tasya Vos (Riseborough) is an unsuspecting killer, but her quiet composure and soft-spoken nature don’t fool her boss (Jennifer Jason Leigh). In her latest mission, Tasya is to implant herself into the mind and body Colin Tate (Christopher Abbott), the boyfriend of a high profile businessman’s daughter. Tasya is then instructed to kill the businessman John Parse, his daughter Ava, and then commit suicide as Colin. After the killings, she is to detach from Colin’s brain and resume her life as Tasya. However, the multiple implants Tasya has undergone throughout the years are starting to tear at her psyche, slowly torturing her own life and jeopardizing her ability to make it out of the mission alive.

For a film that is so dependent on the performances of its lead actors, the expectation for a top-notch cast is exponentially high. Christopher Abbott exceedingly delivers as a conflicted man whose thoughts are at constant battle with an invisible force. Andrea Riseborough’s commitment to her role is also commendable, further solidifying my belief that she is among the most underrated actors of today. Both Abbott and Riseborough bring restraint and bold expression to a uniquely shocking script, making Possessor a thrill to watch and an impossible film to forget.

Distributed by NEON, Possessor is now playing at the Vineland Drive-In and other select theaters.
