'Mean Girls' Writer Opens Up About 'Painful Experience' Working With Tina Fey And DEMANDS Compensation For The Franchise

While Wiseman should be out promoting the new musical based on her hit book Queen Bees and Wannabes, instead, the writer is opening up about the "painful experience" which led to her losing the royalties to her original story.

The 54-year-old writer was paid $400,000 after signing her deal with Paramount, but has yet to see a single dime related to the hit Broadway musical, video game adaptation or the 2011 made-for-tv sequel on Freeform.

Wiseman also called out her former co-writer on the project for being a "hypocrite."

"Over the years, Tina’s spoken so eloquently about women supporting other women, but it’s gotten increasingly clear to me that, in my own personal experience, that’s not going to be the experience. You don’t just talk about supporting women, you actually do it."

Fey originally asked to buy the film rights to Wiseman's Queen Bees book after reading the New York Times Magazine cover story about it. The two met with film and TV producer Lorne Michaels and he decided it would be best to work on the film together. The movie was filmed and eventually retitled, Mean Girls.

Wiseman's original contract included "net profit points" — extra cash dependent on how well the movie does at the box office.

However, the studio has reportedly told her they have made no net profits from Mean Girls and have actually incurred so much extra cost there is nothing past that threshold left to share with her.

The author's lawyers are now wanting to audit Paramount’s books.

Wiseman's lawyer Ryan Keech told the Post, "It is nothing short of shameful for a company with the resources of Paramount to go to the lengths to which it has gone to deny Ms. Wiseman what she is fairly entitled to for having created what has become one of the most iconic entertainment franchises of the last 25 years."

Fey and Paramount have yet to respond.
