The press and social networks are awash with images of topless Vladimir Putin fishing in Siberia with his Minister of Defence Sergei Shoigu, a native of Tywa, the republic where they went on a holiday trip.
But why do Putin's image-makers persist with this particular bit, the fishing? This time, including the underwater chase after a pike? One explanation could be that they have in mind the macho man James Bond fighting the baddies underwater in the 1965 'Thunderball' with Sean Connery. (wiki on the film)
To the giggling Russians, the idea of going on a fishing trip inevitably evokes the cult 1960s comedy 'The Diamond Hand' with a staged fishing episode, when one crook is scuba-diving with a net full of live fish that he puts on the hook and the second is on shore supposedly ready to knock out the 'target.' It all backfires. (wiki on the film)
