SLIDERS third season will probably be filmed in Hollywood rather than in
Vancouver which is where most of the first two seasons were shot.
It seems that this decision was a mutual one made at the end of the second
season's filming by all parties involved.
A future episode will feature an Earth which was overrun by in 1947 by
extraterrestrials who landed in Roswell, New Mexico. Look carefully for a
secondary character we haven't seen yet during the second season. [Invasion]
