Template:Show Good Luck Charlie is an original Disney Channel sitcom, which premiered on April 4, 2010. The series was created by Phil Baker and Drew Vaupen, who wanted to create a program that would appeal to entire families, as opposed to children only.
It revolves around a Denver family, the Duncans, as they try to adjust to the births of their fourth and fifth children, Charlotte "Charlie" Duncan and Toby Duncan. In each episode, Teddy Duncan (Bridgit Mendler) creates a video diary containing advice for Charlie about their family and life as a teenager. Teddy tries to show Charlie what she might go through when she is older in the video diaries for future reference. Each video diary ends with Teddy (or someone else from the family, even Charlie) saying the eponymous phrase, "Good luck, Charlie".
Among other decisions, executives included adult-centric scenes and changed the series title from Oops to Love, Teddy and finally to Good Luck Charlie in order to ensure the series would appeal to all family members. Good Luck Charlie premiered on Disney Channel in the United States on April 4, 2010. It premiered in Canada on April 5, 2010, the United Kingdom and Ireland on May 14, 2010, and in Australia and New Zealand on July 23, 2010. Good Luck Charlie was renewed for a second season, with production beginning in August 2010 with a season premiere on February 20, 2011. A feature-length Christmas Disney Channel Original Movie based on the series entitled Good Luck Charlie, It's Christmas! began production in March 2011 for a December 2011 premiere.
On August 29, 2011, Disney Channel announced that they had renewed the series for a third season. The third season premiered on May 6, 2012. On July 12, 2012, Disney Channel announced that they renewed the series for a fourth season.
The series centers on the Duncan family, who are still adjusting to the birth of their fourth child, Charlotte "Charlie" Duncan (Mia Talerico). When parents Amy (Leigh-Allyn Baker), a nurse, and Bob (Eric Allan Kramer), an exterminator, return to work, they ask their three older children—PJ (Jason Dolley), Teddy (Bridgit Mendler), and Gabe (Bradley Steven Perry)—to help raise their little sister. At the same time, Teddy, PJ, and Gabe try to deal with school and typical social challenges in their life.
The events of each episode become material for a video diary Teddy is making for her younger sister. Teddy hopes the videos will provide useful advice for Charlie after they have both grown up and Teddy has moved out. Also at the end of each video, she (and/or other cast members) states, "Good luck, Charlie" or may even say it indirectly such as "Wish them good luck, Charlie." During the movie, Amy reveals to Teddy that she is pregnant with her fifth child, which Teddy is trying to adjust to but this story plot is not carried into the actual series until the third season. In the third season, Amy gives birth to a baby boy, Toby.
