FILM: You won't know whether to laugh or cry at the world premiere of Baby Jane?, an over-the-top interpretation of the original over-the-top, cult classic. Described as "if the most obscure filmmaker David Lynch… the hilarious Mel Brooks… and the funniest cross dressing BBC television show, Little Britain, had a baby… it would be Baby Jane?"
