Here's a much younger Eliza (about 12 years old!) singing in "This Boys Life"

Check the eyeglasses! As the movie progresses, she eventually loses them to show she's a bit older. Not a big part for her, but she's definitely working on her "little smart-*ss" persona in the film as Robert DiNiro's youngest daughter. (By the way, in this film, he's a real abusive jerk.) This was probably her second film, and would later work with DiNiro in "City By The Sea".
