16 Best Guest Stars In Red Dwarf

16. Ainsley Harriott - GELF

Perhaps one of the more difficult guest stars to recognise was the former Ready, Steady, Cook host, Ainsley Harriott. He played a GELF (Genetically Engineered Life Form). This role involved being inside of what was a very heavy, very warm bodysuit of fur.

He plays this role in series seven but unless you're told he's there, it would be impossible to tell. Lister marries one of the GELFs and Ainsley is in attendance but isn't the lucky GELF lady herself - sadly.

A notable guest by any measure, and the boys from the Dwarf later had a second interaction with Ainsley on a one-off commemorative show called Can't Smeg, Won't Smeg.
