Instinct is a 1999 American psychological thriller film, directed by Jon Turteltaub, and starring Anthony Hopkins, Cuba Gooding Jr., George Dzundza, Donald Sutherland, and Maura Tierney.

The film examines the mind of anthropologist Ethan Powell who had been missing for a few years, living in the jungle of Uganda's Bwindi Impenetrable Forest with mountain gorillas.

Eventually it is revealed that during the course of Powell's stay with the gorillas, they accepted him as part of their group; he was attempting to protect his great ape family when the poachers arrived and started shooting them.

At the end of the film, Powell escapes from prison using a pen to dig out the lock on a window, and heads back to Africa.
