Re: Red Dwarf series 9 (or is it 10?) in 2012 confirmed by Craig Charl
Was there any reason Chloe Annet had such a small part in the show? Was she off filming something else? Or perhaps they really did want to set up a potential story arc for Lister in a future series at the time they wrote it.
I think it might be explained in the DVD commentary or something. Presumably she'd moved on and wasn't that interested in doing a full-length return. Take it for what it's worth, but the IMDb shows a 5-year gap in her TV and film acting work before Back to Earth, so maybe she'd stepped away from the business or was concentrating on the stage.
Plus it did work well for the overall story. Last I heard (someone PLEASE correct me if this is wrong) she isn't involved in the new series either, but again I may be dead wrong.
