British actor Daniel Day-Lewis has won the Oscar for best actor for his role in Lincoln becoming the first person to win the accolade three times.
The recognition for his performance in Lincoln capped off a night in which Adele won the Oscar for best original song along with other British successes in costume, make-up and animation.

Day-Lewis joked about playing Margaret Thatcher in his acceptance speech but later said that he found it hard to imagine "playing another historical figure" and that he was ready to rest for a "couple of years".
He first won the award for his role in the 1989 film My Left Foot and then again in 2007 for There Will Be Blood.
The most coveted award of the night for best picture went to Ben Affleck's thriller Argo repeating its earlier success at the BAFTAs and Golden Globes.
Jennifer Lawrence took the award for best actress for her performance in Silver Linings Playbook.
In her excitement to collect her award, the actress tripped over her dress on the stairs leading up to the stage. She reassured the audience in her acceptance speech that only her pride was hurt.
Anne Hathaway and Christoph Waltz were named as best supporting acts for their roles in Les Miserables and Django Unchained respectively, while Ang Lee triumphed in the best director category for Life Of Pi.
Adele's victory marked the first time a James Bond film has won in the music category.
She gave a live performance of her hit single Skyfall during the ceremony as part of a tribute marking 50 years of Bond films.
She thanked her songwriting partner Paul Epworth, who came on stage with her, for "believing in me all the time", adding in a shout out to her partner Simon Konecki, "And my man, I love you baby".
Dame Shirley Bassey also made an appearance singing the theme from the 1964 film Goldfinger.
The Oscar for animated feature film was awarded to Brave - a cartoon set in the Scottish Highlands and featuring the voices of Billy Connolly, Emma Thompson and Julie Walters.
The award for costume design went to Jacqueline Durran for Anna Karenina.
The British designer said the win was "completely overwhelming" and paid tribute to her children who were "fast asleep in England".
There was another UK win when the Oscar for make-up and hairstyling was won by Lisa Westcott and Julie Dartnell for Les Miserables.
