Lifetime went behind the Bell on Monday and unveiled what (allegedly) happened behind the cameras of our favorite childhood sitcom. But instead of Zack Morris running the show, this time it was all about Screech - and the story from outcast Dustin Diamond's perspective. The Unauthorized Saved by the Bell Story, based on Diamond's tell-all memoir, began with the gang -- Dylan Everett as Mark-Paul Gosselaar, Sam Kindseth as Diamond, Tiera Skovbye as Elizabeth Berkley, Julian Works as Mario Lopez, Alyssa Lynch as Tiffani-Amber Thiessen, and Taylor Russell McKenzie as Lark Voorhies - pulling up to their first mall tour unaware their lives were about to change.
