The official documentary done in honor of the 60s series called "Lost In Space Forever" which was released just before this crap movie's theoretical street date, included a short little segment at the end with Jonathan Harris back as Dr. Smith, Bill Mumy as Will and Dick Tufeld returning as the Robot's voice (ironically he also performed the voice of the new robot in the movie as well.)
Its hard to believe just how good they still were, even after more then 30 years. They'd aged, but still hadn't lost any of their charm.
