Kevin Bacon admits he has struggled to get used to being famous.
The X-Men: First Class star told The Sun he was desperate to be well-known when he was younger, but has found it difficult getting recognised everywhere he goes.
He said: "I have had to adapt, although it has been a long, long time, to being well-known.
"It was something I always wanted, always fought for and desired so strongly as a kid.
"At the same time you can't describe what living in a fish bowl is like until it happens."
Kevin, 52, who first shot to fame in 1984's Footloose, said he was not worried about portraying a mutant Nazi in the X-Men prequel, which also stars James McAvoy, Michael Fassbender and January Jones.
He said: "I am not afraid of playing bad guys. I have no personal image that I am trying to uphold."
