At 8, she landed the role of Kate, an orphan girl in the touring Broadway musical Annie, the 20th Anniversary. For the next eight months, she toured the United States and Canada with the musical, during which time Ludwick gave eight performances per week. In 2003, Ludwick appeared as the character Yumi in thirteen, an autobiographical drama film based on American film actress Nikki Reed's experiences as a 12 and 13-year-old girl. In 2004, Ludwick appeared on Movie Surfers, a Disney Channel mini-show where four teenagers go behind the scenes to report on Walt Disney-related films. Three years later in June 2007, Ludwick began work on Teen Witch the Musical, a stage musical based on the 1989 fantasy-comedy film Teen Witch. She briefly replaced Miki Ishikawa in the role of Vicky on Zoey 101 for one episode in season 1.
