The Australian actor told The Graham Norton Show that he was grateful his countryman Crowe rejected the part of Wolverine in Bryan Singer's X-Men adaptation.
"We are great mates and I actually owe my career to him because he turned down Wolverine," he explained.
Jackman reprised the role in sequels X2 and X-Men: The Last Stand, as well as spinoff X-Men Origins: Wolverine and an uncredited cameo in last year's Matthew Vaughn-helmed prequel X-Men: First Class.
The actor had previously revealed that his friend Crowe not only turned down the part but also recommended him for the job.
Asked if he had to audition for Les Misérables, Jackman added: "Everyone did. It was the longest audition of my life - it was four hours.
"I have never asked to leave an audition before but had to put the kids to bed."
The Graham Norton Show's New Year's Eve Special airs on Monday, December 31 at 10.35pm on BBC One and BBC One HD.
