Actor Hugh Jackman, who plays the mutant Wolverine in the X-Men and Wolverine films, revealed that his role required him to growl which has subsequently affected his vocal range. 

Speaking at BBC Radio 4's Front Row, he said, "My falsetto is not as strong as it used to be, and I put that down directly to some of the growlings and yelling I did. My teacher at drama school would have been horrified by some of the things I did in Wolverine. I've done some damage to my voice, through playing Wolverine."

It may be noted that Jackman will return as Wolverine in the superhero film Deadpool 3. The film which is currently in pre-production is scheduled hit the theatres on November 8, 2024. Jackman will join the titular character played by Ryan Reynolds in the film. They first teamed as Wolverine and Deadpool in 2009's X-Men Origins: Wolverine.
