Swedish actor Dolph Lundgren, 68, says getting a second medical opinion after a kidney cancer health scare was the decision that turned everything around. He has opened up about the experience in a new documentary, "Dolph: Unbreakable," which is now getting attention from critics and audiences.

Lundgren also has a memoir out going into detail from his career, including the story behind a widely remembered red carpet confrontation with Jean-Claude Van Damme. The documentary and book come out at the same time, giving fans a rare glimpse at the health battle and life the Swedish actor has rarely discussed publicly.
