American actor and comedian Neil Patrick Harris did not live up to expectations as the host of the 87th annual Academy Awards held at the Dolby Theatre on 22 February in Hollywood.

The How I Met Your Mother star kicked off the show with a magical music number, but was not as entertaining during the show.

"Tonight we honour Hollywood's best and whitest - I mean brightest," Harris joked.

In a shocking move, Harris, a frequent Tony Awards host, hosted part of the night's ceremony in his underwear as part of a tribute to Best Picture nominee Birdman.

The 41-year-old Gone Girl actor topped the trending word on Twitter and was compared to comedian Ellen DeGeneres who hosted the Oscar Awards last year.
