Plot
The Lionhearts focuses on the behind the scenes life of MGM's mascot, Leo Lionheart, and his family. The series shows the Lionhearts living in a normal house and living a normal life just like non-celebrity families. Most of the members of the family are named after famous MGM movie stars. The characters first appeared on a series of Sing-Along children's videos released by MGM in 1997. The original character designs (especially those of Spencer and Kate) were greatly modified for the TV series. Ashley Tisdale provided the voice of Kate in the Sing-Along videos, while Charles Rocket was the voice of Leo, Lana was voiced by Debra Jo Rupp and Chris Marquette did the voice of Spencer.
