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 name.
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.
