4. Hugh Jackman – X-Men (2000)

Hugh Jackman as Wolverine in X-Men

It may seem hard to believe nowadays, but once upon a time, Hugh Jackman was considered a radical casting decision for X-Men‘s Wolverine. The Australian actor had primarily acted in dramas up to that point, and hadn’t honed his skills as an action star. He was a relative unknown outside of Australia, and his casting in X-Men proved hugely controversial.

In fact, Jackman was the second actor cast in the role: Dougray Scott was initially cast, but a busy shooting schedule and unfortunate injury saw the role pass to Jackman. The Australian was considered both too tall and too handsome to play Wolverine, with many believing that he didn’t embody the spirit of the character. However, as soon as X-Men was released, these doubts were immediately dispelled.

Jackman’s turn as Wolverine is undoubtedly one of the most perfect castings of all time. Not only did he redefine what people considered possible for the character, but he embodied him entirely, changing the very fibre of how Wolverine was perceived. Though he was initially considered a poor choice for the role, Jackman’s Wolverine in the X-Men franchise is one of the most iconic castings ever.
