The country superstar made her acting debut in an episode of How I Met Your Mother in 2010, and the following year, she made her motion picture debut in Soul Surfer, which premiered on April 8, 2011 -- 10 years ago today. The movie lines up well with Underwood's Christian faith, but the faith-based elements of the film wound up creating controversy before the film even premiered. Soul Surfer tells the story of Bethany Hamilton, the champion teen surfer who lost her arm to a shark attack in 2003 at the age of 13. The movie was adapted from Hamilton’s autobiography, and Underwood played the role of Sarah Hill, Hamilton's best friend and a youth counselor at her church. Hill's friendship and encouragement helped Hamilton return to surfing against all odds (Hamilton got back on the pro surfing circuit just months after losing her arm).
