Some listeners of a certain age may still best know Kirk Cameron as the charming Mike Seaver from the 1980s sitcom “Growing Pains.” But since then, he has invested his time and energy into faith and family-focused films, television shows, and live events. He joins the Busted Halo Show to discuss his latest movie called “Lifemark,” which centers on adoption. Cameron is an executive producer and plays the adoptive father in the film.
