Tim Allen, Sigourney Weaver and Alan Rickman star in this delightfully daft send-up of TV sci-fi. The has-been cast of a “Star Trek”-like television show are suddenly kidnapped by an alien race who believe their TV show broadcasts were real. Watch for subtle and not-so-subtle jabs at the Trek franchise and pop culture in general: The “rock monster” is a mock tribute to William Shatner, who reportedly desperately wanted rock monsters in THE FINAL FRONTIER but had to cut his vision due to budgetary limits, while the evil warlord Sarris was named after unforgiving film critic Andrew Sarris.
