Mia Talerico is an American child actress. She plays Charlotte \"Charlie\" Duncan, the title character of the Disney Channel sitcom Good Luck Charlie. The series premiered April 4th, 2010. \r\n\r\nOn Disney Channel's Good Luck Charlie, Talerico plays Charlotte \"Charlie\" Duncan, a \"surprise\" addition to the Duncan household. On the show, Charlie's three teenage siblings help their working parents raise Charlie while the family adjusts to having a baby again. \r\n\r\nGary Marsh, entertainment president of Disney Channel Worldwide, says hiring Talerico, who was ten months old when she was cast, was their biggest risk while creating the show.  Like most series involving baby actors, the creators of Good Luck Charlie had originally searched for twins.  Hiring two babies would allow longer work days without violating child labor laws as well as the ability to substitute one child for the other if one is unavailable. However, the show makers were unsuccessful in finding an appropriate set of twins and decided to cast Talerico.  \"It's like flying without a net,\" says Marsh. \"She may have a bad day and we can't shoot and it'll cost us tens of thousands of dollars,\" said Marsh. \"But so far, so good. She's the most obedient actor I've ever worked with. \"\r\n\r\nTalerico's personal milestones are reflected in her character. \"We want to do stories that come from real life, so we talk to Mia's mom about what's going on with Mia, what she's into, what words she's saying, and we incorporate the things she tells us into our stories,\" says Phil Baker, co-creator of Good Luck Charlie.
