Jordana Brewster explains why 'Fast and Furious' is her least favorite in the 'Fast' franchise

Nobody knows Mia Toretto better than Jordana Brewster, who has played the character in six of the nine Fast and Furious films.

Ahead of F9, the 41-year-old actress joined Collider's "Collider Ladies Night" series to break down her career. That included an admission that the fourth installment, 2009's Fast & Furious, is her least favorite. Here's why:

"I haven't rewatched 4, but to me, it's very grey. It's set in L.A., Paul's in a suit, I'm in this red dress, and I have bangs and I'm just very sad and [angry] at him. I just feel like I don't remember that one super fondly. ... It's always a bummer when I'm not—as I've said, I love being part of the action. I don't just like being a talking head, talking with the boys. It's fun to get in there and get dirty."

Brewster debuted as Mia in the first Fast film in 2001, The Fast and the Furious. Mia is Dominic Toretto's (Vin Diesel) sister who falls in love with Brian O'Conner, played by the late Paul Walker. She sat the second and third films out, then returned for Fast & Furious.

Mia also had a presence in Fast Five (2011) and Furious 7 (2015), and she will again in F9: The Fast Saga once it hits theaters June 25.

With Collider, Brewster explained where she feels Mia is at her strongest throughout the record-breaking franchise:

"It's a tie between 1 and 5, I have to say. I never give myself credit when I'm working on something and when it comes out, I'm always like, 'I wish I could have done that better. I wish I could have done this better.' But I recently looked back at 1, and I was actually really proud of myself because I was this kid in college and I worked on how I speak, I worked on making myself a little bit more tough, and I think I really come off as a little bit tougher and I’m really proud of that, and I came off as very grounded. "And then I think I lost that as the franchise evolved, and I was kind of prissy in 4 and then back to really knowing what I want in 5, and I tried to retain that in 9 because it’s really important to me that Mia’s very centered and grounded, and I lost sight of that in 4. But also, it was [a] reintroduction to everyone. But I think 5 had every element in it. It had the, 'Okay, we're gonna build a family,' it also had the, 'We're gonna go out there and kick [butt] and we're gonna get fearless,' and, 'Both of you shut up and stop arguing and we’re gonna come together.' It had all of those elements in a really sort of nice, cohesive way and we’re getting back to that with 9."

Walker died Nov. 30, 2013, from a car crash in the middle of filming Furious 7. By that film, Brian and Mia were married with a son, Jack. Mia reveals in the seventh movie that she's pregnant with their daughter, and Brian leaves behind the high-risk lifestyle. 

Brian is still alive in the Fast universe, and fans went crazy when a glimpse of Walker made its way into the second F9 trailer:
