Otherworld (1985 TV Series) - Episode 1 "Rules of Attraction"

Part Stargate, part Sliders, the 1985 CBS sci-fi series only ran for eight episodes before being cancelled. A family in visiting an Egyptian pyramid during a specific planetary alignment is transported to a parallel world, with Jonathan Banks playing the antagonist. This is the entire show (except for the first few seconds of the title sequence) exactly as it premiered on WCBS on January 26th 1985, including commercials.
