Red Dwarf is a British science fiction comedy franchise created by Rob Grant and Doug Naylor, which primarily consists of a television sitcom that aired on BBC Two between 1988 and 1999, and on Dave since 2009, gaining a cult following. The series follows low-ranking technician Dave Lister, who awakens after being in suspended animation for three million years to find that he is the last living human, and that he is alone on the mining spacecraft Red Dwarf—save for a hologram of his deceased bunkmate Arnold Rimmer and "Cat", a life form which evolved from Lister's pregnant cat.
