Kristen shared with MTV about channeling her inner rock star, “I need to be thinking that this is the hardest job that I’ll ever have to do, because I need to make myself nervous a little bit. And I was intimidated by the singing part, even though it’s not as much as what [Dakota Fanning] has to do. Joan has such a distinct sound, and I didn’t want to sound stupid. I didn’t want to sound like I didn’t sound anything like her.”
