I think she is so hot, but she does seem like some Fi/Te type.
The Barnum or Forer effect is the tendency for people to judge that general, universally valid statements about personality are actually specific descriptions of their own personalities. A "universally valid" statement is one that is true of everyone—or, more likely, nearly everyone. It is not known why people tend to make such misjudgments, but the effect has been experimentally reproduced.
The psychologist Paul Meehl named this fallacy "the P.T. Barnum effect" because Barnum built his circus and dime museum on the principle of having something for everyone. It is also called "the Forer effect" after its discoverer, the psychologist Bertram R. Forer, who modestly dubbed it "the fallacy of personal validation".
I know a women whom Winstead strongly resembles (they are running the same software), and I type the woman as an LII sx-first or sx-second.
From Winstead's stills, I'd have said IEE-Fi Delta, but watching the video, I can see Ti. Lots of Ti and lots of sex appeal. She doesn't have the regimentation of LSIs, so LII.
ISFP
Would agree with Fi/Te, seems rational also from the clip posted
Sensory + Ethical. Fe/Ne valuing. Rational. ESE.
Probably EIE>IEE.
She seems to see herself as hard-working (possibly a rational thing, but she seems to think she's more relaxed than in the past), and with a passion for the performing arts, which is arguably a NF club focus. Her biography doesn't seem especially exciting (I can't see any controversy, or much that makes her stand out as an actor, other than maybe being pretty active (industrious?)).

"Mary Elizabeth Winstead: From Mercy Street to Cloverfield Land" in Interview Magazine (9 March 2006)
I think my drive to work has gone up a bit since I’ve gotten older. The more I work the happier I am. I’m also finding a lot more roles that are exciting and challenging for me on a more regular basis.https://en.wikiquote.org/wiki/Mary_Elizabeth_WinsteadInterview with Glamour Magazine (26 April 2017)
There’s always going to be challenges and barriers, but you have to be adaptable and go, "OK, if that’s not going to work for me, then this is a passion I have as well." I was passionate about a lot of things in the performing arts, so I was lucky ballet wasn’t the only love in my professional life. I wanted to perform, and I didn’t feel ballet was going to allow me to do that to the extent that I wanted to. Acting seemed like a good transition from that.I’m probably more laid-back in a lot of ways. I was very type-A as a kid, and I wanted to be the best at everything. Now I’ve definitely learned that this is not the best [quality to have. You need to be able to screw up and learn from it.
