'When Calls the Heart' stars Kevin McGarry and Kayla Wallace are mixing business with pleasure! To celebrate their new film, 'Feeling Butterflies,' the real-life couple is interviewing each other for ET. The actors tease their new film, premiering March 12 at 8 p.m. ET/PT on Hallmark Channel. They take turns asking each other questions about the flick, but also reveal sweet stories about their personal lives and careers. Kevin and Kayla recall getting their first life-changing acting opportunity, what they've taught each other, the animals they'll never work with on-screen, what they'd be doing if they weren't actors and their favorite part about working together.
