Neil Patrick Harris set to host Oscars in 2015

Actor Neil Patrick Harris has been roped in to host the Oscars in 2015.

The star of TV comedy How I Met Your Mother announced the move by posting a cheeky video on Twitter.

In it, he says "I'm in!" as he gets off the phone, before circling the words "Host the Oscars" on a bucket list.

The 41-year-old, known to many for Doogie Howser MD, has hosted the Tony Awards and the Emmys, but he said this realised a lifelong ambition.

"To be asked to follow in the footsteps of Johnny Carson, Billy Crystal, Ellen DeGeneres, and everyone else who had the great fortune of hosting is a bucket list dream come true,'' Harris said in a statement released by the Academy of Motion Picture Arts and Sciences.

“We are thrilled to have Neil host the Oscars. We have known him his entire adult life, and we have watched him explode as a great performer in feature films, television and stage. To work with him on the Oscars is the perfect storm, all of his resources and talent coming together on a global stage," read a joint statement by show producers Craig Zadan and Neil Meron.

The Academy Awards will be held Feb 22 at the Dolby Theatre.
