She plays the female Jack Reacher, kind of.

Im not competing fight-wise with superheroes, she laughs.

It is so exciting to see these superheroes fight one another.

The [human characters] are, like, Im just gonna make some phone calls.

No weapons, no superpowered gear, no SHIELD agency beyond you.

Youre on the run.

In theJack Reachersequel, Smulders plays Major Susan Turner, a confirmed military badass with Ranger training.

Turner and Reacher know and respect each other…and theres the spark of something more.

These are two people who dont have much time to date, says Turner.

They started a relationship just by being friendly and helping each other out, and that blossomed into more.

Reacher decides to seek out Turner, and maybe ask her out.

Now they have to work together.

Initially, that goes horribly wrong, and they have to reconfigure themselves.

She becomes a big part of the story, says Smulders.

So now were in this weird family dynamic.

At the same time, theyre all being hunted, all being chased.

Eat your heart out,Modern Family!
