Listen to any interview where Hugh talks about his family. They are beyond precious. Particular favorites include his wife laughing about how ripped he got for X-Men Origins: Wolverine ("Look at you. I don't even recognize you any more. Now get in the bed!") and the story he tells about a character he pretends to be for his daughter during playtime right before bed. The character's name is "Bucky" and his daughter was very small and couldn't pronounce words correctly so the name always came out "Fucky" when she got excited. You can imagine she said this in public once and poor Hugh got some very confused looks.
And he also is adamant that, as much as he loves the character, he's getting older and is looking forward to Passing the Torch to the next actor that gets to wield the adamantium claws. That's remarkably humble for an actor who has become world-famous for a role.
