Dougary Scott was cast, but left for work on Mission Impossible:II
Aaron Eckhart was considered
Viggo Mortenson was considered
Mel Gibson was considered
Russel Crowe was considered
Edward Norton was considered
Keanu Reeves was considered
Jeane-Claude Van Damme was considered
Gary Sinise was considered
So, I think Jackman is the best Wolverine ever and I'm glad he was casted, but if he wasn't out of all of the top I would have chosen Russel Crowe.
And for all those who were complaining over Jackman's height, you shouldn't have it really doesn't matter, and by the way Gary Sinise, Mel Gibson and Jean-Claude Van Damme are the closest to Wolverine's height
Look out for The Wolverine next year
