- The film is adapted from the biographical literature "Soul Surfer: A True Story about Faith, Family, and Re-Standing on the Surfboard" published in 2004. The prototypes of the film and the biography are surfer Bethany Hamilton.
- In addition to the biographical literature, the source of the story in the film also includes interviews with Hamilton’s family and friends by the crew, many of which are not written in the book.
- AnnaSophia Robb, who plays Hamilton, has been wearing a green sleeve on her arm during the shooting, so that the post-production staff can turn her into a one-armed person. There are 450 shots that require post-processing.
- The film was shot in Hawaii in early 2010, and some additional shots were taken in Tahiti in August of the same year.
- Due to the low production cost, the producer originally only planned to show the film in 300 cinemas. However, after the film was shot, the producer felt that the quality of the film was excellent, so he made additional investment and expanded the scale to 2,000 cinemas.
- The production cost of the film is only about 15 million U.S. dollars, but the cost of printing posters, advertising and publicity is as high as 26 million U.S. dollars.
- The film was shot in only 40 days, and the whole film was shot using 35mm film .
Soul Surfer behind the scenes gags

[first lines, narrating]
Bethany Hamilton: I was born in Hawaii to two die-hard surfers. How could I not have salt water in my veins. They say home is where the heart is, and for most people that consists of four walls and a welcome mat. But for me, it's the ocean, with the warmth of the sun on my skin. Two brothers, that's my answer when anyone asks why I'm so competitive. And of course, there's my best friend Alana. We spent more time wet than we did dry, my mom was convinced that we were mermaids. From the moment I caught my first wave, I knew I wanted to be a Pro Surfer. Nothing else seemed to matter. Surfing is my passion, my way of life. The stoke I get from riding a perfect wave is pure joy. But like my dad always says, life is an adventure. And sometimes you wipe out and end up in the impact zone.

[last lines, narrating]
Bethany Hamilton: I was born to surf. This is why I wake up at the crack of dawn everyday. This is why I endure belly rashes, reef cuts and muscles so tired they feel like needles. And I've learned life is a lot like surfing. When you get caught in the impact zone, you need to get right back up. Because you never know what's over the next wave. And if you have faith, anything is possible, anything at all.
