Hugh Jackman has been playing Wolverine for something like 17 years now.
He's turned him into the most iconic X-Men character.
But in a recent interview with the Associated Press, Hugh revealed that he studied wolves prior to shooting the first X-Men BECAUSE HE DIDN'T KNOW WOLVERINES EXISTED:
I didn't even know there was a wolverine. I literally, embarrassingly did about two weeks of research on wolves. I was rehearsing for three weeks and I was shooting, so I was kind of on my own. I remember going past an IMAX in Toronto, and there was an IMAX documentary about wolves, and so I thought, 'I'll go and see that.'
It's just too fucking good. When he showed up to shoot, director Bryan Singer was like, "WTF, dude?":
[Singer] said, "Are you sort of walking funny, what's going on?" And I said, "I've been doing this thing with wolves," and he goes, "You know you're not a wolf, right?"
I said, "Well, there's no such thing as a wolverine." [Singer said] "Go to the zoo, dude." I literally didn't know it existed.
