Channing Tatum loves a good tearjerker! "They're kind of cathartic," The Vow's leading man told at the film's Los Angeles premiere. "They can teach you a lot. I watched love stories growing up, and they teach you how to go about relationships." So what can viewers learn from The Vow? "If you love somebody, then it's all worth it," Tatum said. What a romantic! Catch The Vow when it hits theaters this Friday, February 10th.
