Swedish actor Dolph Lundgren, 68, says seeking another doctor's view after a kidney cancer health scare was the decision that turned everything around. He has spoken publicly 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 famous red carpet confrontation with Jean-Claude Van Damme. The documentary and book arrive together, giving fans a close look at the health battle and life the Swedish actor has kept largely private.
