Holly is the ships computer on board Red Dwarf. He is played by Norman Lovett as a disembodied head floating on a black background.  Holly prides himself on the fact he had an IQ of 6,000, but after three million years by himself, he had become computer senile, or as he put it, "a bit peculiar".  It is Holly who releases Dave from stasis and has to inform him that the crew are all dead.  'He's dead, Dave, everybody is dead, everybody is dead, Dave.'
