The 300 star had never really surfed in his life when he was offered the chance to play real-life water baby Frosty Hesson in the Curtis Hanson film, and he needed quite a bit of persuading to sign on for the role.
Learning to pilot a helicopter at the time, Butler decided to buzz the coast to watch real surfers at play.
He tells WENN, ""I had the script and I used to get on at the Santa Monica airport and fly up and down Malibu and the coast and I saw all the guys on paddleboards and surfboards and I went, 'Look at this. What am I thinking? I need to get a place in Malibu and spend a bit of time here. I need to take this movie, and I need to learn how to surf.'
""That was when I decided to do this movie, when I was in the helicopter. I always try to retain a sense of wonder and humility. Looking at the task at hand it was quite a daunting experience.""
