Dennis Quaid has proven to be one of Hollywood’s most durable stars, but he has also undergone personal challenges: In 2007, his then-week-old twins nearly died after a medication error. It was while sitting with them in 2009 that Quaid agreed to portray Tom Hamilton, the real-life father of world- champion surfer Bethany Hamilton, in the new film Soul Surfer. It’s a role Quaid says helped him believe in God again.
