Boyhood has come away from the 35th annual London Film Critics Circle Awards as the biggest winner of the night, with three prizes; best film, best director for Richard Linklater and Patricia Arquette as the best supporting actress of the year.

The other three main acting awards also went to American actors who triumphed at last week’s Golden Globes: Birdman‘s Michael Keaton was named the best actor, Julianne Moore was voted the best actress for playing a woman with early-onset Alzheimer’s Disease in Still Alice and JK Simmons won his latest best supporting actor prize for his turn as a tyrannical music teacher in Whiplash. Another American, Wes Anderson, was honoured for his screenplay for The Grand Budapest Hotel.

British winners, at the ceremony at the May Fair Hotel in central London, were limited to the parochial categories set up specifically to honour them: Jonathan Glazer collected the award for the best British Film of the Year for Under the Skin, which was recognised at the British Independent Film Awards in 2013. The film’s composer Mica Levi won the award for the best technical achievement. The Oscar-nominated Rosamund Pike was named the best British actress, for Gone Girl. An actor overlooked by everyone since Cannes, Timothy Spall, took home the award for the best British actor, for his portrayal of the painter JMW Turner and the best Young British Performer was Alex Lawther, from The Imitation Game, which despite being one of the most Oscar-nominated films of the year, didn’t even make it onto the London critics’ top ten list. And the director Yann Demange was named the breakthrough British film-maker, for his well-received Northern Ireland drama ’71.

The Circle picked Citizenfour, about the American intelligence fugitive Edward Snowden, as the best documentary of 2014, while the Russian drama Leviathan, continued to destroy everything else in its path, to take the prize for the best foreign-language film.

The actress Miranda Richardson was also on hand to be honoured with the Dilys Powell Award for Excellence in Film.
