Not everyone is happy about Lifetime’s upcoming “Saved By the Bell” movie.

The behind-the-scenes film, “The Unauthorized ‘Saved By The Bell’ Story” will be loosely based on Dustin “Screech” Diamond’s book “Behind the Bell,” which he admitted was ghostwritten and fabricated. Diamond’s former co-star Mark-Paul Gosselaar recently expressed his issues with the book on HuffPost Live saying, “Everything I’ve heard about his book is that it is negative, and I don’t remember those things because my experience on the show was very positive.” Now it looks like another former cast member is speaking out against the book and the film.

Dennis Haskins, who played Mr. Belding, principal of Bayside High, told TMZ that he doesn’t trust the movie since the memoir was so exaggerated. “There just wasn’t any craziness,” Haskins said. “It was like, yeah, people dated each other. Okay, so what?” When asked if he thought the movie’s purpose was to stir up drama, Haskins added, “and to make some money.”

At the end of the day though, Haskins has no interest in watching the story told on TV. “I was there. I don’t need to watch it. I know what happened and what didn’t happen.” We wonder though if he was just a little curious about watching the first five minutes.
