Following the first clip released earlier this month, Lifetime has debuted the first trailer for their upcoming TV movie The Unauthorized Saved by the Bell Story, which airs Monday, September 1 at 9 PM ET on Lifetime.

While Saved by the Bell became a big hit, and made stars out of cast members Mark-Paul Gosselaar, Mario López, Dustin Diamond, Lark Voorhies, Elizabeth Berkley and Tiffani Thiessen, this TV movie explores all of the turmoil behind-the-scenes between these young actors. Check out the latest footage before tuning in on Labor Day.

With casting by the original Saved by the Bell series' casting director, Robin Lippin (Lizzie McGuire), Dylan Everett (Degrassi: The Next Generation) is set to play Mark-Paul Gosselaar in the role of mischievous ringleader "Zack Morris." Sam Kindseth (Shameless) is Dustin Diamond, everyone's favorite geek and loveable sidekick "Screech." Julian Works (Paranormal Activity: The Marked Ones, Modern Family) fills the shoes of superstar Mario López as the hunky jock "A.C. Slater." Alyssa Lynch (The High Jumping Witch) plays the role of America's favorite sweetheart, Tiffani-Amber Thiessen, who originated the part of Kelly Kapowski. Tiera Skovbye (Supernatural, Girl in Progress) takes on the role of talented beauty Elizabeth Berkley and her beloved character "Jessie Sapano." Rounding out the cast is Taylor Russell McKenzie (Blink) who will portray Lark Voorhies and her on-screen persona, the privileged "Lisa Turtle."

The Unauthorized Saved by the Bell Story is produced by Front Street Pictures and Ringaling Productions Ltd. for broadcast on Lifetime. The movie is executive produced by Harvey Kahn (Flowers in the Attic) and Stephen Bulka (Dear Mom, Love Cher). The film is directed by Jason Lapeyre (Restless Virgins) and the teleplay is written by Ron McGee (The Nine Lives of Chloe King).
