Ben Affleck's Argo wins best film at Britain's Baftas

LONDON (AFP) - Iran hostage crisis drama Argo won the best film prize at Britain's Bafta awards on Sunday, in a further boost for US actor-director Ben Affleck's movie at the Oscars later this month.

Affleck also won the best director award at the biggest night of the British film industry, while Daniel Day-Lewis was named best actor for Lincoln and France's Emmanuelle Riva won best actress for Amour.

Anne Hathaway won best supporting actress for her performance in British musical Les Miserables while Christoph Waltz won best supporting actor for his role in Quentin Tarantino's blood-soaked Western Django Unchained.

Celebrities defied sleet, rain and wind to parade down the red carpet for the ceremony at the Royal Opera House in London, with the Baftas widely seen as a key bellwether for the Academy Awards.
