The words “starring Robin Williams” hardly inspire film-goers with confidence these days. After a career that includes the dramatic highlights of Good Morning Vietnam, The Fisher King and Dead Poets Society, and the amenable comedy of Mrs Doubtfire, he has more recently made a slew of films over which it would be kind to draw a veil. But he’s back on terrific form in World’s Greatest Dad, one of the most original and funny comedies released this year.

Marc Quinn is used to making a spectacle of himself. In Self (1991 and ongoing), a life-sized cast of his head was filled with his own blood. It was a stark and sobering reflection on what we all share, the universality of the most basic of human elements. But with the works in his new show Allanah, Buck, Catman, Chelsea, Michael, Pamela and Thomas, "spectacle" becomes the operative word, and universality is nowhere to be found.
