St Trinian's 3, rated 15 by the BBFC was a 2020 Movie distributed by Entertainment Film Distributors. And was marketed as a big crossover movie, like "Eat The Rich". Unfortunately, also like Eat The Rich, it only grossed £5 Million on a £30 Million Budget.
The film involved St Trinian's School, crossing over with the worlds of Madea and Little Britain, and guest starring RuPaul from RuPaul's Drag Race. The film's tagline is "This time, the Girls are back in town".
Starring Rupert Everett as the principal of St Trinians, Miss Camilla Fritton. Managing a school full of girls is the least of his worries when she encounters a very angry woman called Madea Simmons who is portrayed by Tyler Perry who threatens her with extortion and violence, and of course Anne from Little Britain portrayed by David Walliams.
The movie was an astounding failure despite having such a star-studded cast. Only grossing £5 Million on a budget of £30 Million.
