Hugh Jackman recently starred in the musical "The Greatest Showman" but had the fortune to work with some people very dear to him: his kids. Jackman's 17-year-old son Oscar and 12-year-old daughter Ava were able to enjoy a brief moment in front of the camera, acting as spectators in the crowd. His son had previously had a cameo in another of his father's films, "Australia," where he had a boring experience and is not interested in pursuing acting.
