Neil Patrick Harris has teased his Oscars-hosting duties in a new Academy Awards video.

He also admits to watching previous ceremonies to find ways of keeping the show fresh and exciting for audience members and viewers at home.

"It's a shockingly long process of writing a single joke," Harris says. "Because you have to say it. It doesn't sound right, you change one verb or you change one parenthetical and see if it's better with a bigger set up. All for an 'I showed my weiner in Gone Girl' joke."

The video also shows behind-the-scenes footage from Harris's rehearsals, while he hints at some magical skits during the show as well.

"We're actually going to be using people in interesting ways, he says. "There is going to be a musical number at some point in the show. I'm a magician, so I wouldn't be surprised if there was a hint of magic. I fear I've said too much."
