 "'Boyhood', 'Grand Budapest Hotel' big winners at BAFTA 2015")
Boyhood, a moving, groundbreaking film about growing up, was shot with the same actors for over 12 years, bagged the best film, best director for Richard Linklater while Patricia Arquette, 46, won the best supporting actress for the portrayal of a doting divorced mother of two kids.
Accepting the BAFTA (British Academy of Film and Television Arts) trophy, an emotional Arquette said Linklater had made a film like no other, which had broken "the rules of cinema... You made an ordinary story extraordinary."
She dedicated her award to late filmmaker Tony Scott, a man who "changed my life because he really taught me how to listen to myself as a girl and as an actress. Every single idea that I had, he'd say, 'That's a brilliant idea, let's do it.' So I love you England for giving us Tony Scott."
The award for leading actress went to Julianne Moore for her unbearably moving role of a woman succumbing to Alzheimer's in Still Alice.
She took to the stage and emotionally thanked the female members of her family, insisting she felt compelled to mention them during her first ever BAFTAs speech - because they hail from the UK.
"Thank you for including me among these beautiful performances both British Felicity, Rosamund and American Amy and Reese I'm honoured to be honoured with you tonight. Film is a collaborative medium, there's no way you can give a performance by yourself and the thing I value most about my job is the creative partnership with others," she said.
Eddie Redmayne triumphed in the best actor category for his portrayal of Stephen Hawking in The Theory of Everything after beating Benedict Cumberbatch (The Imitation Game), Ralph Fiennes (Budapest), Jake Gyllenhaal (Nightcrawler), Michael Keaton (Birdman).
