Just in case you’ve forgotten, Red Dwarf is set three millions years into the deepest of deep space, in a lonely, alienless Universe, well past the natural life span of the now distant human race. Despite this, and as early as series 1, we’ve always had our fill of guest stars, from artificial intelligences, to human created GELF monstrosities and haughty and / or insane holograms. The apparently narrow scope for guest characters has never been a problem.
Series X is now over and done with and every single episode featured at least one guest character of some description. They’ve all combined to make for a unique series, with encounters of the like we’ve never before, as well as ones expanding on past stories. So join me now, if you will, as I trawl through every single guest character, get to know the actor a little better (search for them on IMDb), assess them (needlessly and overtly infuse the piece with my own opinions) and finally try to work out which ones, if any, we are likely to see again come a potential Red Dwarf XI.
