I remember some people weren't happy with the casting of Hugh Jackman as Wolverine because 1) he was Australian and 2) he's much taller than Wolverine. Actor Dougary Scott was first scheduled to play Wolverine but he opted to be in Mission Impossible 2. Dougray Scott is also not Candanian (he's scottish) and he's also tall. So I guess the filmakers didn't care about sticking to those details. Honestly it didn't matter to me. Hugh Jackman really caputured the character of Wolverine.
