While standing in for Janice Long on BBC Radio 2, Craig Charles revealed that he will return as lead character David Lister.
He said: "I can now announce we are going to be doing two more series of it starting in January next year... I got the call today. They said 'Craig, can you do it?', I said 'I'll sort it out'. So I will be able to do it in January."
Meanwhile, Chris Barrie, who plays Arnold Rimmer, told the Coventry Telegraph: "There are plans afoot to have a tenth series.
"I find it very hard to call it a tenth series, because that obviously means we're calling the Easter special from last year the ninth series. But yes, certainly, I would say some more new Red Dwarf product. There are plans afoot to get that into gear."
He added: "I think of 'Back To Earth' as a sort of 21-year celebration, really, as a proper three-part special. But yes, it would be nice to do, and hopefully we will, another six half hours.
"I don't really know anything more than I'm saying, believe me. I do know plans are afoot, but that's all I can say. In terms of the direction of the show, I don't really want to see it change that much. I just want more strong storylines, probably in a half-hour format."
