The Fly II is a 1989 American science fiction horror film directed by Chris Walas. The film stars Eric Stoltz and Daphne Zuniga, and is a sequel to the 1986 film The Fly, itself a remake of the 1958 film of the same title. Stoltz's character in this sequel is the adult son of Veronica Quaife and Seth Brundle, a scientist who became a human-fly hybrid as a result of an experiment gone awry, played by Jeff Goldblum in the 1986 remake. With the exception of footage of Goldblum from the first film, John Getz was the only actor to reprise his role, with another actress filling the Geena Davis role as Quaife in the opening birth scene. Unlike the previous film, this film received negative reviews.
