Pernell: I had six seasons of playing the eldest son on (Bonanza). Six seasons of feeling like a damned idiot, going around -- me, like a middle-aged teenager, saying, "Yes, Pa," "No, Pa" on cue. It was downright disgusting -- such dialogue for a grown man. I felt I wasn't being taken seriously as an actor, and that's like death to one's talent...Stuck as Adam Cartwright, I was only able to use about one-tenth of my ability.
