Michelle Rodriguez has been with the Fast and Furious franchise since its inception, so when she says Charlize Theron plays the meanest bad guy the gang has ever seen in Fast 8, she knows what she's talking about.

"We're gonna go hard on this one," Rodriguez told ET's Deidre Behar, referring to the upcoming installment in the blockbuster series. "Charlize Theron is, I think, the most powerful villain this franchise has ever seen."

Theron stars as the gun-toting baddie Cipher in the hotly anticipated action flick, and while not much is known about her character, the 41-year-old Oscar winner has proven time and again that she can hold her own as a weapon-wielding warrior woman -- most recently as Imperator Furiosa in the universally acclaimed Mad Max: Fury Road.

Rodriguez said she only got to work with Theron for a couple of days, but the experience solidified the 38-year-old actress' opinion that the Fast and Furious franchise needs more women.

"In order for me to be a part of the franchise in the future, they need to up the ante on the females," Rodriguez shared. "I mean, it's like a sausage factory in this thing."

"I just need some more feminine energy," she added. "We need some more women on the good side."

Before Fast 8 races into theaters on April 14, 2017, Rodriguez is starring in the new family drama Milton's Secret. The drama, adapted from the 2008 novel of the same name by Eckhart Tolle, tells the story of a young boy (William Ainscough) who is the target of bullying and falls into an emotional despair.

Rodriguez, who has been an outspoken advocate for anti-bullying campaigns, opened up about how why the film spoke to her, and how her outlook on life has changed since she was a teenager growing up in New Jersey.

"I'm more sensitive now because I've always been a very tomboyish… I just never gave a f**k about words," Rodriguez explained. "Now I understand that I have to respect words and words are powerful and they are dangerous and they hurt people."

Milton's Secret, which also stars Donald Sutherland, David Sutcliffe and Mia Kirshner, is in select theaters and available On Demand and Digital HD on Sept. 30.
