Lifetime is taking us all back to Bayside High School for a behind-the-scenes look at the TV show that made every girl in America fall in love with Zack Morris.

The Unauthorized Saved by the Bell Story will follow the experiences of the six stars of the show — Mark-Paul Gosselaar, Dustin Diamond, Mario Lopez, Tiffani-Amber Thiessen, Elizabeth Berkley and Lark Voorhies — and their subsequent rise to fame, "exposing the challenges of growing up under public scrutiny while trying to maintain the squeaky clean image of their popular characters both on and off-screen," according to a release.

Saved By the Bell's original casting director, Robin Lippin, put together the cast for the movie, set to debut Sept. 1.

Dylan Everett (Degrassi: The Next Generation, Supernatural) will play Gosselaar. And Sam Kindseth (Shameless), Julian Works (Modern Family), Tiera Skovbye (Supernatural) and relative newcomers Taylor Russell McKenzie and Alyssa Lynch will portray Diamond, Lopez, Thiessen, Berkley and Voorhies, respectively.

Saved By the Bell ran on NBC from 1989 to 1993 and followed the antics of high schoolers Zack Morris (Gosselaar), goofy Screech (Diamond), jock A.C. Slater (Lopez), cheerleader Kelly Kapowski (Thiessen), brainy Jessie Spano (Berkley), and shopaholic Lisa Turtle (Voorhies). But it lives on in reruns on TBS — and in our hearts.

The Unauthorized Saved by the Bell Story was written Ron McGee (The Nine Lives of Chole King) and directed by Jason Lepeyre (Restless Virgins).
