[on the importance of having the right chemistry of either a series' or a co-star]: No. Of course, it's more fun if you and the other person work well together, but it's not a requirement. I mean, you're acting. You can have difficulties with each other because of ego or insecurity or advertising and billing, things that can annoy people or hurt their feelings, but you don't let it get in the way of the work. That's the thing.
