The X-Men star feared he had broken his neck during a daring scene in which his character swings out of a train carriage.
Jackman's injuries weren't severe, but the incident was enough to scare his wife, Deborra-Lee Furness, who made him reassess the amount of dangerous work he does on set in future.
"In the film, there's a scene where I swing from inside to outside a train and my neck got caught. I thought I had broken it." Jackman says he is now smarter about using a stunt double.
"It was one of those moments when my wife looked at me and said, 'What are you doing? Enough playing in the schoolyard! You are not invincible!'"
The 44-year-old actor also revealed in a recent interview with GQ magazine that his character's famous Adamantium claws are dangerous in real life too, just not
as dangerous.
"They've cut deep more than once. And not just me", he said of Wolverine's weaponry.
