Clint: (on joining OLTL) I had no idea they did a complete show each day or that you were expected to learn the amount of dialogue we learned. When I did a movie, we took ten weeks to shoot it, and I'd have only two or three pages of dialogue a day. I remember one day Erika Slezak and I had over 50 pages of dialogue, and we did it.
