She took the exhaustion all in stride, preferring to look at it as research.

I feel like Im probably the coolest one because its such a character piece.
This is actor candy.
This isnt like all of the other Marvel superhero properties or movies youve seen.
This is a very well-crafted, developed, psychological thriller.
How does it compare to the comics?
I think she is as developed in the show as she is in the comics.
I was so excited.
Thats the journey that we go on with her.
Shes a very reluctant superhero.
When we meet her, is she taking on cases as a detective?
Just to make a buck, honestly.
Shes not trying to save the city or really do anything.
Shes making money to buy whiskey.
She doesnt have to exist and socialize.
How do her powers manifest?
She represses a lot of her abilities.
Shes a bit of a brawler.
She can fly, but not well … at all.
So she doesnt do that often, because shes so bad at it.
Shes just not a very good superhero.
Shes a real misfit.
Shes a real fing misfit.
Thats got to be fun for you.
Its so much fun.
Its a great part.
Shes so cool and so strong.
Shes got all of this power.
I mean, its one of the most exciting roles Ive ever seen, man or woman.
As soon as I got the part, I was fight-training and boxing.
I can throw a punch now.
At the beginning, I had no idea what I was doing.
I was always like, What do I do with my thumbs?
I enjoy the stunt portion of the show.
I had no idea I would, from the first episode.
I was like, Oh my God.
This is so thrilling.
I think we were doing a night shoot.
Usually around two or three in the morning, you start to go down.
Whats the feeling been like on set?
Ive been working harder than Ive ever dreamed Id have to and learning a lot.
I dont know how Ill adjust right away, back to normal life.
Im going to probably sleep for a week.
Its been so thrilling.
Every day, its been, Is this really happening?
Yep, its really happening.
How long have you been shooting?
Ive been here for eight months.
Thats a long time!
Yeah, Ive never done anything that long.
The last show I did was a half-hour, so it was less time.
This is a big show, so it takes longer to shoot an episode.
Whats it been like working with David Tennant?
David is heaven, and hes such a wonderful actor.
This whole cast and the show is really on another level.
Everyone is so uniquely special and right for their parts.
For me, Im here every day, and then someone else will come in.
Ill get a lot of one-on-one time with David Tennant.
Then I get a lot of one-on-one time with Rachael Taylor.
David is constantly impressing me.
His acting is like jazz.
Hes doing one thing, and then hes doing something else.
He can do a five-page scene like its nothing.
Im just continually impressed by him and his work ethic.
Hes just a great guy.
It sounds like it will be dark.
Where does this fall compared to Jane choking on her vomit onBreaking Bad?
This is unlike anything Marvel has done before.
People are going to be surprised by that.
I think your mind goes to a certain place when you think of Marvel.
I think the most exciting thing about them is their ability to execute things really well.
This is them doing something completely different.
This is all really right for that book and where Jessica started.
The tone is pretty spot-on.
That sounds right withDaredevil.
I think its proportional for what that is.
This is equally standing on its own.
Its like, Whoa, what the f is this?
Marvel has like 9,000 characters.
They could do a horror movie tomorrow and call it Marvel.
They can do anything.
Its really exciting for me to be a part of them doing something so different.
Is this a binger?
I think so because its serialized.
It feels like a 13-hour movie.
I havent seen the show, so who knows?
You might need a breather.
This show feels more like a movie than any serialized show I can think of.
What are the hard days on set for you?
We have pretty long hours.
Did you get hurt at all?
I got a little bit of whiplash.
It sounds like your lack of sleep might help the character.
Thats part of it.
Jessica Jones doesnt sleep much either.
All of it really feeds the character.
Shes got odd hours.
It works for the role.
