The 63-year-old actor won numerous accolades throughout the 2015 awards season and many, probably he himself, thought he had a good shot at taking home an Oscar for his leading role in 'Birdman'.

Keaton may have had to return empty-handed, but 'Birdman' scored four wins at the ceremony including best director for Alejandro Gonzalez Inarritu and best picture.
