TV tonight: escape into deep space with the Red Dwarf crew

Red Dwarf: The Promised Land
9pm, Dave

Rimmer, Lister, Kryten and the rest of the Red Dwarf crew are back for a feature-length special of galactic mishaps and absurd adventures. Craig Charles reprises his role as the radioactively reborn vending machine repairman who, in this one-off, encounters a trio of cat clerics who worship him as their god. But they are being hunted by feral cat leader Rodon (Ray Fearon) and only Lister can lead them to safety. Forever oddball, the return of Red Dwarf is a suitably escapist break in these uncertain times.
