Based on a bestselling comic memoir by two young Russians, Pavel Tetersky and Sergei Sakin, SA (Suzie) Halewood's Bigga Than Ben is a sketchy, intermittently funny, enterprising comedy about two young Russians, self-styled 'Moscow scum', living by their wits in London. They're played by British actor Ben Barnes and Russian pop star Andrei Chadov. Both carry conviction.
