At the tender age of five, Mackenzie, caught the 7th Heaven casting director's eye because she was the most polite child to audition for the part. She walked in, shook everyone's hand and introduced herself and landed the role of Ruthie Camden.
Mackenzie Rosman: Yes! I definitely want to continue acting on-screen. I love acting, and I've been doing it for so long. Although I love 7th Heaven, I definitely need a change. I've been playing the same character for so long! I want to audition for some big-screen roles, and hopefully that will involve traveling at the same time.
Mackenzie Rosman: I don't know how I'd be able to go to school every single day, though. I'm not used to it. It makes work so much better. Before it was like, Oh, I gotta go to work today, and now it's like, Oh, yay! It's 7th Heaven today!
Mackenzie Rosman: Fortunately, I learn my lines fairly easily. Playing the same character for so long, I really only have to read the scene two or three times and I've got it.
Mackenzie Rosman: My family and I saw Jessie [Jessica Biel] over Christmas, but I haven't seen anyone else. I talked to David [Gallagher] a little while ago, but we're all just busy and I've got school. I don't even drive because my mom won't let me, which is kind of ridiculous!
Mackenzie Rosman (About her 7th Heaven character, Ruthie): We're both kind of the same — a little bit bitchy. It's not that she's smarter than I am, but she knows more. I'm not really the one in my family who knows everything that's going on, because I don't really pay attention. Ruthie is craftier than I am.
Mackenzie Rosman: I don't know what I want to be when I grow up. It's funny people ask me that and I don't know what to tell them. I really like what I'm doing right now. I'm not bad at it, so I might as well keep doing it.
