Unauthorized tell-alls about beloved 90s shows seem to be the new focus for Lifetime made-for-TV films, as the "Beverly Hills 90210" movie has just been confirmed by the network, once more getting no official approval by the show's producers or any of its stars.

Lifetime has recently confirmed that the "Beverly Hills 90210" movie is now entering production, and while there's still no cast, some of the people involved have already been announced - even before the network's most recent unauthorized biography of a beloved television show, the one dedicated to "Full House," has even aired.

According to The Hollywood Reporter, the "Beverly Hills 90210" movie will focus on the first four seasons of the show (it ran for a total of ten), when a lot of controversy sparked among cast members and there was supposedly a lot of drama behind the scenes, particularly at the time star Shannon Doherty drifted from the show produced by Aaron Spelling.

Fifteen years after the end of the show in 2015, the "Beverly Hills 90210" movie is set to un-muddle the waters of the first few seasons of the show, when the cast and crew crashed on a regular basis while the series became one of the most iconic of the decade.

As Fox News reports, there are already many well-known bouts of drama from the show in that period, though the TV movie's focus is unknown.

Variety reports that while the "Beverly Hills 90210" movie hasn't gone through casting yet, this is what's known about the people behind it: its executive producers will be Peter M. Green ("Mean Girls 2") and Howard Braunstein ("The Informant!"), while the producer will be Christian Bruyere ("A Girl's Best Friend"), from a screenplay written by Jeff Roda ("Love Liza") and directed by Vanessa Parise ("PopFan").

The "Beverly Hills 90210" movie is the latest of its kind to be produced at Lifetime, following one about "Saved by the Bell" (so this would be the second Tiffani Thiessen show to get its own tell-all movie) and an upcoming "Full House" one.
