London: US-based Indian actress Freida Pinto, who will be starring in John Ridley's six-part limited TV series "Guerrilla", has started filming for it here. The show, which will also feature actor Idris Elba, is based on black activism in London in the 1970s. "I'm thrilled to be working with an artiste like John Ridley who has written these compelling scripts filled with thoughtful and complicated characters," Frieda said in a statement. Frieda will be essaying the role of Jas Mitra, a passionate and politically driven individual who is part of a radical underground cell that helps liberate a charismatic convict from prison to lead the street fight against social injustice in 1971 London. Along with Ridley and Elba, the executive producers will be Patrick Spence and Katie Swinden for Fifty Fathoms, Tracy Underwood for ABC Signature, and Michael McDonald for Stearns Castle.
