The Fly

Considered fairly gruesome in its day, the original 1958 The Fly looks like Mister Rogers' Neighborhood compared to this 1986 remake. Jeff Goldblum and Geena Davis star as Seth Brundle, a self-involved research scientist, and Veronica Quaife, a science-magazine reporter. Inviting Veronica to his lab, Seth prepares to demonstrate his telepod, which can theoretically transfer matter through space. As they grow closer over the next few weeks, she inadvertently goads Seth into experimenting with human beings rather than inanimate objects. Seth himself enters the telepod, preparing to transmit himself through the ether -- but he doesn't know that he is sharing the telepod with a tiny housefly.
