No writer of fiction could devise a character as beguiling as Rajesh Ji, a paunchy private detective who patrols the mean streets of Kolkata solving murders, prying into the messy lives of divorcing couples and thwarting endless dodgy scams. Rajesh is also a dedicated family man with a passion for dance and the abiding conviction that his smooth moves may yet bring him stardom. Philip Cox's documentary has a great central subject but also provides a fresh, offbeat perspective on modern India and the thousands of everyday stories that build a vivid portrait of a society in transition. Stephen Frears is set to direct a fictional version of the Rajesh story ­ catch the original while you can. Part of Glasgow Film Festival 2012: Stranger than Fiction.
