Midway through the filming of the fifth series, Jason told Sullivan that he wished to leave the show in order to further his career elsewhere. Sullivan thus wrote "Who Wants to Be a Millionaire?", which was intended to be the final episode and would see Del accepting a friend's offer to set up business in Australia, leaving Rodney and Albert behind. Plans were made for a spin-off entitled "Hot-Rod", which would have followed Rodney's attempts to survive on his own with help from Mickey Pearce, but leaving open the prospect of Del's return. Jason then changed his mind, and the ending of the episode was changed to show Del rejecting the offer.
