The 34-year-old Irish actor
appeared on Jimmy Kimmel Live
on Tuesday, and revealed why he decided to shave his head months after wrapping on the filming of the erotic book-turned-movies. "It's for work," Dornan -- who is rumored to be starring in Robin Hood
next year -- said of his haircut. "In my early '20s, I used to have a shaved head quite a lot. So, I know that I don't have one of those weird shapes."
