Starring Miley Cyrus, Greg Kinnear, and Liam Hemsworth, The Last Song is a too heavy on subplots and a too light on actual content. The casting directors unearthed some hidden gems in supporting actors Bobby Coleman and Carly Chaikin. Coleman plays Cyrus’ younger brother and warmed my cold black heart in ways that only a small child can, especially when sharing the screen with his terminally ill father (Kinnear).
