What Chuck Connors said about The Rifleman:
"on his Lucas McCain character] Lucas was a righteous character, despite all the violence. We had the benefit of the father-son relationship, so I could have a little scene at the end of the show where I would explain to Mark, essentially, that sometimes violence is necessary, but it isn't good. And there was a lot of violence on "The Rifleman" (1958). We once figured out that I killed on the average of two and a half people per show. That's a lot of violence, but it was always covered by the scene with the little boy. And he would say, in essence, "Gee, you won Pa". And I would say, "Wait a minute son. You never win when you kill someone. It demeans you, it takes something away. People have got to learn to do away with violence and guns, and to love each other". And the viewers would forget the fact that I had killed three people during the show, because of the tender epilogue with Mark [Johnny's favorite scenes]. The warm father-son relationship was the heart of the program, and not only did we perform it, but Johnny and I became very close friends.
[About the character he was best-known for] I can never get rid of "The Rifleman" (1958), and I don't want to. It's a good image. Basically, [the show] was the simplicity of the love between the father and the son. That was the foundation. The rifle was for show, but the relationship was for real. There was some violence, but at the end, I would explain to the boy that the violence was not something we wanted to do, but had to do.
[In 1992, about being typecasted because of "The Rifleman" (1958)] If you're ever being typecasted--as most of us are-- that's a great way to be typecasted. So, "The Rifleman" is still popular with a lot of people, and I'm proud to be associated."
