"I am still kind of a normal kid," she told Denver's CBS4 This Morning. "I look at movies differently now. When I go to see movies with my friends, I'm much more critical. They kind of put tape over my mouth so they can enjoy the movie!"
Robb is back in her hometown this week, where she'll be signing copies of the book "Bridge To Terabithia" on Saturday.
The young actress said that she enjoyed the challenges she faced making the movie.
"Bridge of Terabithia" is a story about two unlikely friends who create a magical kingdom together.
"It's a heart-wrencher," Robb said. "I think this film has a really good balance of imagination and also it talks about family life and school, and bullies, but mainly friendship."
Robb said it's hard to be away from her friends, and she does miss certain not-so-glamorous school activities.
"It's kind of hard trying to keep up all the time, it's hard knowing that some school event is coming up like the dissection of frog for instance, and I'm going to miss it because I'll be gone," she said. "But I always get to come back and see my friends, and I still get to be with them."
