Kristen Stewart's Latest Film Role Leaves Her In Tears

Kristen Stewart was photographed having a tough time on the set of her new movie, Anesthesia

Kristen Stewart was having a tough time on the set of her new movie Anesthesia, yesterday.

The 23-year old actress, who kept out the cold in a chunky knit and large beanie, was photographed looking teary-eyed and tired whilst filming in New York.

However, we're guessing the Twilight star was merely doing her job (and it looks like she was doing it well, we might add), rather than having a real life altercation with fellow actor Sam Waterson with whom she was filming.

The movie, directed by Tim Blake Nelson, focuses on a group of New Yorkers whose lives are all affected by the same philosophy professor. Kristen is said to have a minor role in the film, which isn't surprising given the many other projects she is working on, namely Camp X-Ray which is currently in post-production.

And Ms Stewart's busy schedule shows no sign of slowing down as it has also been reported that the young starlet has also landed a role in new action comedy, American Ultra.

Kristen is said to be starring opposite Jesse Eisenberg in the movie, and will play Phoebe - the girlfriend to Eisenberg's character Mike.

Directed by Nima Nourizadeh, the film follows Mike and Phoebe as their lives are turned upside down one night after Mike's past comes back to haunt him and he becomes the target of a government operation set to wipe him out.

We're definitely excited at the prospect of seeing Kristen in a comedy. Let's hope filming gets underway soon...
