Although I never watched it, I remember this series, and we have it to thank for many of today’s stars and Hollywood wrecks.  On this date in 1989, the Disney Channel launched The All-New Mickey Mouse Club.  This is where all of these stars essentially began their careeres:
Chad Allen, J.C. Chasez, Britney Spears, Ryan Gosling, Christina Aguilera, Justin Timberlake and Keri Russel
