The closing credits for the programme varied series by series. The first series used peeling labels featuring the names of the cast and crew, mirroring the opening sequence, but these had to be updated with every new episode, making the process very time-consuming; from the second series the credits switched to a standard rolling format. The third series featured additional symbols. For the fourth series, these designs were replaced with white lettering on a black background. The fifth series had a black and white background, but the sixth series reverted to the black one. For the seventh series, the credits scrolled against a freeze frame of the final scene.
