MOSCOW (AFP) - The director of a Soviet television serial about an undercover spy dubbed the Russian equivalent of James Bond and admired by millions including Vladimir Putin has died, cinema officials said Thursday. Tatyana Lioznova, who made the television series Seventeen Moments of Spring that is still widely admired today, died aged 87, the deputy head of the Russian filmmakers union Klim Lavrentyev told the ITAR-TASS news agency.
