Our first rehearsal, I think it was Mark and Judy [Greer], and Judy and I were both dancers growing up and poor Mark didn’t know that,” the actress shared. “And he came in and he hated the rehearsal process so much he almost dropped out of the movie.”Obviously, we know that Mark stuck with it and, as it turns out, the scene is Garner’s favorite memory from 13 Going on 30.
