emotional wisdom and intuitive strength.

So what have you figured out about Dave and Alex and also about what Zachary (Knighton) and Elisha (Cuthbert) bring?

JG: Zachary and Elisha are the most experienced actors of the group. They've been in series before and on television before, and that shows. They're not strictly comedians. Damon's a stand-up, Adam (Pally) and Casey (Wilson) are coming from sketch comedy, Casey also from "SNL," and Eliza (Coupe) was a comedy theater performer in New York and then did "Scrubs," so I guess she has series experience too. I think that they bring just good acting chops, and to some extent, they're a little bit the emotional center of the show. Dave, especially, he's the guy we're trying to give stronger, funnier attitudes to play. He's a guy who has funny bad ideas of stuff he should try, like exploring his Navajo heritage. But there are also episodes - and he's happy to do it - where he's the regular guy, and our eyes and ears. And Alex, some of the early time was spent buying back what she did in the pilot, which was hard for a lot of people to process. We've made her that confidently oblivious character. There's a line in episode 111 last year, I forget the exact set-up, where hanging out with Penny and the Italians is too hard and she doesn't want to do it anymore, and Dave says, "You said the same thing about 8th grade." Intellectual stuff, she doesn't have time for. We've made her a little spacey and out of step with the rest of the group. There's a joke in the premiere where she says she doesn't understand half of what her friends say. I think she's Jane's little sister, somebody everybody loves who has a lot of emotional wisdom and intuitive strength, which Elisha has as a person, and we can make her clueless in some ways.
