“Rebel is ridiculous,” Johnson, 26, said in an interview that aired today on “Good Morning America." “There was a lot of improvising. There was a lot of, you know, she would go on runs and rants and I would just be like giggling, crying off camera.”
Johnson said the movie, which hits theaters today, has an important message, particularly for its young female viewers.
“I think it’s about taking the time to just be yourself and, especially for young women, to figure out who you are and what you like,” Johnson said. “And go and do whatever you want all the time.”
