He started acting at the age of 27.
Kevin Hagen: (about the controversial final episode of "Little House on the Prairie") Yes, it was very emotional, and each actor would really have to speak for himself or herself. I can't do that for them. As for me, the over-riding emotion was anger. I thought it was an absurd end to a television series about people who cared about each other and their town--people who would never dynamite their homes just so others could never live in them. Besides, Walnut Grove was and remains a town where the Ingalls family actually lived. The series owed its existence to the books written by Laura Ingalls Wilder. It held fairly close to the essential facts of the Ingalls family history, except for this one final, totally unbelievable moment.
