Oscars 2017: The Top three awards go to

Affleck beat fellow nominees, including Ryan Gosling of the musical 'La La Land' as well as Andrew Garfield for 'Hacksaw Ridge,' Viggo Mortensen for 'Captain Fantastic' and Denzel Washington for 'Fences'.

Emma Stone won the Oscar for best actress for the whimsical musical 'La La Land,' the most honoured film of the night.

The 28-year-old won her first Oscar in a field that included former winners Meryl Streep and Natalie Portman, as well as Ruth Negga for interracial historical drama 'Loving' and French actress Isabelle Huppert for rape-revenge thriller 'Elle'.

"Moonlight," a poignant coming-of-age story set in the tough projects of southern Florida, on Sunday won the best picture Oscar -- but not before the prize was first given in error to musical "La La Land."

The mistake -- only corrected after the producers of "La La Land" had come on stage to accept the award -- was a stunning end to the film industry's biggest night.
