SHOT by more than 12 cinematographers over a four-year period, Winged Migration is a beautifully mounted nature documentary offering an intimate portrait of birds, their mating rituals and migratory patterns.

The film travels the length and breadth of the globe, from Antarctica to the Arctic Circle and back again, to follow various species on their epic journeys north and south for the winter season, employing all manner of transport including hot air balloons and aeroplanes to capture the birds in flight.

Nominated for this year's Best Documentary Oscar, the film, from French actor/director Jacques Perrin, has delighted critics and viewers alike.

You are sure to be left pondering just how the film was shot for a long time after the final reel ends thanks to incredible cinematography, such as when the camera follows a lone goose through a winding canyon.

Winged Migration even has its tear-jerking moments, when we see the birds getting picked off by predators.

Harbour Lights Picture House, Southampton - until 29th October.
