'FlashForward' was on the outs when I was approached with 'Happy Endings.' I literally got the script on a Friday, and on Saturday morning I met with David Caspe, Jamie Tarses, and the Russo brothers. I took the role on that Saturday, and on Monday I was doing a table read. It all happened very fast, but it was super exciting.
I've had friends whose boyfriends I meet, then they break up and I end up staying buddies with the boyfriend. In this day and age with social media and Facebook, Twitter, it's really impossible to escape people that you've been involved with. In a weird way, it makes it easier for everyone to stay friends because you're just sort of stuck there.
'FlashForward' was a dream come true. I had auditioned for David Goyer for 'Blade: Trinity' and didn't get the part, but I guess he became a fan.
I can tell you, if you shoot in the rain you're going to have a lot of voice ADR to do after the movie and voice looping, stuff like that.
At one point, I was in a place where it didn't feel like it was going to happen, and I was feeling pretty down on myself. But I stuck to it, and now I have a hit comedy on my hands. You've got to keep plugging away at it. If you really believe in yourself, you can definitely make it happen.
