Once they were mere tots: we’ve captured their first steps on a Hollywood red carpet. Taylor Lautner doing cartwheels, Jaden Smith on his dad’s arm, pre-teens Joseph Gordon-Levitt, Shia LaBeouf and Freddie Highmore, little Chloë Grace Moretz and Dakota Fanning and her baby-faced sister Elle when no one knew how famous they would become. Take a journey back in time.
