“I turned the script down for years,” says Will Smith of Michael Mann’s biopic.

“I couldn’t see the road from Will Smith, Fresh Prince of Bel Air, to Will Smith, Muhammad Ali.”

That road? The same road Ali ran. Eating the food Ali ate. Learning to Box the same way Ali boxed. Training five days a week for 12 months. Bulked up by 35lbs to match the former Heavyweight champ’s 220lbs.

Smith’s transformation is extraordinary – and his performance gives us both the myth and the man, not to mention the most concussive ring-rumbles ever thumped on celluloid.

Greatest moment: “Ali, bomaye! Ali, bomaye!”
