Life in the spotlight can be tough for celebrities so imagine what it is like for their children. That is the premise of "Gigantic" -- kids of celebrities living in the Hollywood spotlight. Anna Moore and her younger brother, Walt, are the children of a famous Hollywood couple who just returned to Los Angeles after spending two years in Australia. The teens try to live as normal of a life as possible while being chased around by paparazzi. To add realism to the show -- or perhaps just coincidentally -- Grace Gummer, who plays Anna Moore, is the daughter of legendary actress Meryl Streep.
