The BBC explains: "Written by and starring Greg Davies, The Cleaner follows Paul 'Wicky' Wickstead, a state-certified cleaning technician with a very special field of work: as a crime scene cleaner responsible for the removal of any signs of death. Armed with chemicals, scrubbing brushes and cleaning rags, Wicky removes the gruesome mess at the scene of the crime. When carrying out his duties, he stumbles across the strangest of people: from the victim's relatives, employers, neighbours and acquaintances, to occasionally even the murderers themselves. And because he's a sociable type, he sometimes gossips more than he cleans..."
Greg Davies says: "I'm thrilled that this remarkable collection of actors has agreed to appear next to me on screen. Scrubbing up blood in a hazmat suit in front of them will be a pleasure."
Commissioner Shane Allen comments: "Pinched myself when I saw all this comedy and acting royalty in one show. It's all down to Greg's well hewn scripts, which take us in to different character worlds in surprising and funny ways each week as Wicky has a transformative effect on those he comes across. The Cleaner delivers on BBC One's unique commitment to make UK comedy for a mainstream audience."
Vivien Muller-Rommel from producers Studio Hamburg says: "It is a great honour for us at Studio Hamburg UK to produce a show that brings together some true British icons. We couldn't have wished for a better clean-up crew to bring Greg's brilliant scripts to life."
