Katherine Heigl mentioned Reese in a recent interview, saying that she loves watching Reese’s movies:

AP: Since leaving the show, you’ve starred in several romantic comedies. Are you worried about being typecast?

Heigl: They tend to be the movies I watch when I’m home and hanging out and want to relax. I want to watch Kate Hudson, I want to watch Reese Witherspoon, I want to watch all those great movies that make you feel good. So I loved being a part of them and I didn’t mind being typecast, but any time you start to wander outside the box a little bit people start to get confused. … This one is an interesting one because it wasn’t a conscious decision not to do romantic comedy. … The book explores so many different themes that in order to honor it properly and do right by it we couldn’t just turn it into a romantic comedy.
