In 2009 the UK TV channel Dave commissioned a 3 part Red Dwarf special called Back To Earth. At the time it got mixed reviews -- I really enjoyed it. Apparently it was successful enough (probably DVD sales as well as TV audience) that Dave have now commissioned a new full 6 part series!
Apparently it was all meant to be kept quite but Craig Charles, a.k.a. Dave Lister, accidentally let it slip during a recent radio interview and Robert Llewellyn, a.k.a. Kryten, has confirmed the news on his blog. Shooting is scheduled for the end of the year though so we still have quite a wait before series IX hits our screens. Personally I can't wait!
