The gang's all here!

The first look of "The Unauthorized Saved by the Bell Story" has finally arrived, and there's definitely some drama brewing in Bayside.

Check out the sneak peek above!

The TV movie's stars attempt to look like the spitting images of Tiffani Amber Thiessen (Kelly Kapowski), Mark-Paul Gosselaar (Zack Morris), Lark Voorhies (Lisa Turtle), Elizabeth Berkley (Jessie Spano), Mario Lopez (A.C. Slater) and Dustin Diamond (Screech) ... think they succeed?

Judging from this clip, there was a lot of drama both on and off-camera. In the sneak peek, Thiessen (Alyssa Lynch) and Voorhies (Tiera Skovbye) both seem to have a pretty big crush on Gosselaar (Dylan Everett) ... and Lopez (Julian Works) and Dustin (Sam Kindseth) look like they did not get along off-screen.

Of course, take all the drama with a grain of salt. The book is based on Dustin's 2009 memoir, which Gosselaar and his "Franklin & Bash" costar Breckin Meyer dissed Diamond during an interview earlier this week with the HuffPost Live.

"This guy's such a d**k," Meyer said. "I don't know Dustin at all, but like, everything I read… [Gosselaar] and I have talked endlessly about Saved by the Bell. I grew up at the same time, I was acting -- I used their sets one time when I did a pilot… the Dustin Diamond thing is just so silly. It's just so negative and it always bums me out."

We can't wait to see all the drama unfold when the Lifetime movie premieres Sept. 1 -- what do you think of the sneak peek? Sound off below and check out the rest of the "Saved By The Bell" cast then and now in the gallery!
