Kevin Sorbo received his breakthrough leading role as the Ancient Greek mythical demigod Hercules in a series of five television films which aired in 1994 as part of Universal Television's Action Pack. The first film to premiere was Hercules and the Amazon Women which aired in April 1994 and the subsequent films aired later in the year. The ratings success of the films paved the way for the commissioning of the television series Hercules: The Legendary Journeys which started airing in syndication from January 1995 and ran for six seasons. The series made Sorbo an international star and was one of the highest rated syndicated television shows at the time. Sorbo also directed two episodes of the series during its run and co-wrote one episode. Sorbo had a prominent role in the film Soul Surfer released in 2011.
In 2014, Sorbo co-starred in God's Not Dead, a Christian film in which he portrayed an atheist college professor who requires his students to disown their religions on the first day of his class.
On January 5, 1998, Sorbo married actress Sam Sorbo (née Jenkins) whom he met the previous year when she had a small recurring role on Hercules (Season 3, Episode 8 "Prince Hercules"). They have three children: Braeden Cooper (born 2001), Shane Haaken (born 2004), and Octavia Flynn (born 2005). Sorbo is the spokesman and chair of A World Fit for Kids! (AWFFK!), a non-profit organization that trains teenagers to become mentors to younger children.
In 2001, Sorbo was featured on a celebrity edition of the game show Who Wants to Be a Millionaire, winning $32,000; the money was donated to his charity, A World Fit For Kids.
In 2015, Sorbo provided the foreword to Stan Holden's book Giving Candy to Strangers.
In late 1997, while on a publicity tour for Kull the Conqueror and between the fourth and fifth seasons of Hercules, the newly engaged Sorbo experienced an aneurysm in his shoulder which caused three strokes. As a result, he was weakened for the next several years, a condition kept secret from the public while he recovered. During the last two seasons of Hercules (the fifth and sixth, which aired in 1998 and 1999), Sorbo had a reduced filming schedule to accommodate his condition, and more guest stars were featured in the show in order to reduce Sorbo's duties. The strokes, thought to be triggered when chiropractic manipulation of his shoulder released blood clots from the aneurysm, left Sorbo with a permanent 10 percent vision loss, weakness, impaired balance, and migraines. In his 2011 autobiography True Strength, Sorbo revealed the details of his injury and how his wife Sam helped him recover.
In 2013, Sorbo received the Public Leadership in Neurology Award from the American Academy of Neurology and the American Brain Foundation for his efforts raising awareness about stroke. He also received the 2013 Inspiration Honors Award from the Invisible Disabilities Association.
Sorbo is a Christian and attends a nondenominational church, though he grew up as a Lutheran. Sorbo claims that his religious views have caused certain restrictions in Hollywood productions, stating that "there's a negativity towards Christians in Hollywood, and a negativity towards people who believe in God."
In 2014, during an interview with Jerry Newcombe on the radio show Vocal Point, Sorbo defended Mel Gibson against allegations that his 2004 film, The Passion of the Christ, was anti-Semitic with the words: "News bulletin: you did kill Jesus!" Sorbo later stated he could have rephrased his statements but defended his stance.
