Did you spend Saturday mornings watching Saved by the Bell? I never thought much about the behind-the-scenes facets of the squeaky clean sitcom but someone did. The movie explores the challenges and experiences of six unknown young actors placed into the Hollywood spotlight and growing up under public scrutiny while attempting to maintain the images of their popular characters on and off-screen. Lifetime will air The Unauthorized Saved by the Bell Story on Labor Day. It’s currently filming in Toronto.

Original series’ casting director, Robin Lippin (Lizzie McGuire) completed the casting. Dylan Everett (Degrassi: The Next Generation) plays Mark-Paul Gosselaar [mischievous ringleader Zack Morris], Sam Kindseth (Shameless) is Dustin Diamond [geeky sidekick Screech]. Julian Works (Paranormal Activity, Modern Family) stars as Mario Lopez [uber-happy-jock A.C. Slater], Alyssa Lynch (The High Jumping Witch) Tiffani-Amber Thiessen [girl-next-door Kelly Kapowski], Tiera Skovbye (Supernatural, Girl in Progress) is Elizabeth Berkley [smartypants Jessie Sapano] while Taylor Russell McKenzie (Blink) will portray Lark Voorhies [fashion darling Lisa Turtle].
