Screencaps coming soon!

Here is the movie trailer for the upcoming Disney Channel Original Movie Lemonade Mouth, starring Bridgit Mendler and Adam Hicks. The movie, set to premiere on the Disney Channel on April 15th, is about a group of kids who meet up in detention only to decide to start a band together so they make a name for themselves in their school.

Disney Channel will premiere the sophomore season of its hit series for kids and tweens and families, “Good Luck Charlie,” on SUNDAY, FEBRUARY 20 (8:00 p.m., ET/PT). Across all television for 2010, “Good Luck Charlie” ranked as the No. 2 series among Kids 6-11 and Tweens 9-14.

The comedy centers around the everyday trials, tribulations and triumphs of a busy family of six, including what happens when Charlie turns 2, begins potty training, and inadvertently causes a power outage, unplugging the online chatting and gaming plans of her siblings, Teddy, PJ and Gabe (which could prove harmful to the teens’ wellbeing!). Starring are Bridgit Mendler, Jason Dolley, Leigh-Allyn Baker, Bradley Steven Perry, Mia Talerico and Eric Allan Kramer. Among the recurring cast is Raven Goodwin, Shane Harper and Daniel Curtis Lee (Disney XD’s “Zeke and Luther”).

Season Two also includes the first-ever crossover episode for “Good Luck Charlie,” a storyline featuring the cast of Disney Channel’s newest hit comedy series “Shake It Up.”

Just a minor pushback

Previously announced as premiering at the end of March, Disney Channel’s newest DCOM, Lemonade Mouth, has been pushed back to April 15.

The movie, which stars Bridgit Mendler, Adam Hicks, Hayley Kiyoko, Blake Michael and Naomi Scott, tells the story of how a powerhouse band came to be after five uncelebrated students with a passion for music find each other and ultimately become the voice of their generation.

In addition, the soundtrack which features a few songs written by Adam, will be released on April 12th.
