Sliders (Seasons 1–5)

Sliders (1995–2000) is the cult sci-fi series about jumping between universes, and you can watch it online on iFILM. In his San Francisco basement, physics prodigy Quinn Mallory builds a device that cracks open a doorway to an endless string of alternate Earths.

The very first test run goes sideways. Quinn, his booming professor Maximillian Arturo, classmate Wade Welles, and washed-up soul singer Rembrandt "Crying Man" Brown get flung into a parallel world — with the timer that controls each jump knocked off its settings. There's no way home. Every "slide" drops the four into a fresh version of Earth where history took a wrong turn: one ruled by a foreign power, one overrun by dinosaurs, one where their own doubles are living other lives.

Jerry O'Connell leads as Quinn, with John Rhys-Davies as the loud, theatrical Arturo. Across five seasons on Fox and Sci-Fi, the show built a loyal following on the strength of a single addictive question — what if your world had gone another way? Stream every season of Sliders online on iFILM.
