Steve Coogan is to star in a spoof Star Trek show to be broadcast on BBC2 this Christmas.
Coogan will co-star with fellow comedian Rob Brydon in Celebrity Cruise.
They will play actors in a cult sci-fi show who agree to go on a luxury cruise with a group of fans.
BBC2 controller Jane Root told Media Guardian: "They play characters from a '70s/'80s Star Trek-style show.
"The show ended years ago, but they are persuaded to go on a cruise by their fans."
