The only thing the Fast & Furious films rely on more than gasoline to fuel the franchise is testosterone. The eight films are made by men, for men and one of the franchise’s only woman characters has had just about enough.

To commemorate the Digital HD release of The Fate of the Furious, Michelle Rodriguez took to Instagram to announce that she’s out if future installments of the colossal franchise don’t give their female stars more to do.

“I hope they decide to show some love to the women of the franchise on the next one,” wrote Rodriguez. “Or I just might have to say goodbye to a loved franchise. It’s been a good ride [and I’m] grateful for the opportunity the fans [and] studio have provided over the years…One Love.”

Rodriguez has played the hardscrabble Letty Ortiz since the franchise debuted in 2001, and joins Vin Diesel as the only stars remaining from the first film. But as the roles of franchise newcomers Dwayne Johnson and Jason Statham continue to expand, Rodriguez’s character has remained relatively stagnant.

This isn’t the first time the star has accused the Fast & Furious filmmakers of laziness when it comes to writing their female characters. In an Entertainment Weekly profile, Rodriguez pointed out how few exchanges her character has had with Jordana Brewster’s character, despite the fact that they’ve been making these films for 16 years. “I can count on one hand how many lines I’ve had to her,” she said. “I think that’s pathetic and it’s lack of creativity.“

She has a point. Over the years, the franchise has seen the additions of some key female characters, including Charlize Theron and Helen Mirren in F8. But the most compelling storylines still revolve around the male characters, while their female counterparts are reduced to peripheral support.

Rodriguez’s plea comes at a particularly crucial time for Hollywood, as major studios are being forced to reexamine the place of women in the blockbuster landscape thanks to Wonder Woman’s mammoth financial and cultural impact. The Fast & Furious films have long been hailed for their multiethnic ethos, and have helped set the tone for Hollywood’s slow march towards diversity. Rodriguez is hoping they take the wheel one more time.
