Swedish actor Dolph Lundgren, 68, says seeking another doctor's view after a kidney cancer health scare was the decision that saved his life. He has opened up about the experience in a new documentary, "Dolph: Unbreakable," which is now picking up reviews from critics and audiences.

Lundgren also has a memoir out looking back from his career, including the story behind a well-known red carpet confrontation with Jean-Claude Van Damme. The documentary and book come out at the same time, giving fans a close look at the health battle and life the Swedish actor has rarely discussed publicly.
