The Wes Anderson-directed movie won Original Screenplay, Original Music, Production Design, Costume Design and Make Up & Hair at the event at the Royal Opera House in London.

Anderson was unable to collect the prize for Best Original Screenplay, leaving Ralph Fiennes to claim it on his behalf.

The actor read out a message from Anderson, saying: "I have a letter from Wes it goes like this: if Ralph Fiennes is reading this speech it must mean I have won a BAFTA for our screenplay in absentia.
"I was already unhappy to miss this event but now I'm really angry and resentful that I am not there, and I'm furious.

"I blame the Directors' Guild Of America, for requiring my presence in Los Angeles where most likely I have already failed to win a different prize. I extend my many thanks to the British Academy, of which I am a member in good standing and I look forward to very eagerly getting a hold of this award physically in my own hands as quickly as Fed-Ex can possibly deliver it to me."

Meanwhile, 'The Theory Of Everything' won three awards, including Outstanding British Film, while the movie's star Eddie Redmayne claimed the Leading Actor award for his role as Professor Stephen Hawking, overcoming competition from Benedict Cumberbatch, Michael Keaton, Ralph Fiennes and Jake Gyllenhaal.

US star Julianne Moore won the Leading Actress award for her performance in 'Still Alice', thereby beating Reese Witherspoon, Amy Adams, Rosamund Pike and Felicity Jones to the prestigious prize.

Elsewhere, Richard Linklater's 'Boyhood' won the Best Film and Best Director awards.
