This long-running BBC sci-fi series began its fourth season boasting a bigger special-effects budget and the addition of a new character: a female android played by Judy Pascoe, the real-life wife of Robert Llewellyn (aka Kryten). Returning for more interstellar misadventures -- now in the 23rd century -- are Dave Lister (Craig Charles), obnoxious hologram Arnold Rimmer (Chris Barrie) and the rest of their off-the-wall Red Dwarf shipmates.
