There's another X-Men movie coming out (What!?! A movie about comic book  superheroes? It will never work.) The movie is based on a comic from the early 80's called Days of Future Past, which is set in a dystopian future. The remaining X-Men decide to try to alter their present by sending someone back in time to fix things. In this movie that person is Wolverine, played by Hugh Jackman.

So to promote the movie, they sent Hugh Jackman back in time. 

OK, this sounds like a really dumb idea- to make Hugh Jackman pretend that he's gone back in time to interview himself in 1999- but it actually kind of works. I mean, as an interview.
