In the recently-released teaser clip for the film, which is out in the USA on 21 August, the Twilight star is a shadow of her red carpet self in the role of Phoebe.

Sporting neon-coloured hair with roots and an alternative sense of style, she looked more like a character from acclaimed 90s TV series My So-Called Life.  

But, actually, the 25 year-old is the main star to the projects's male character, portrayed by Jesse Eisenberg.

Directed by British talent Nima Nourizadeh, the film tells the tale of a 'stoner' whose past comes back to haunt him when he becomes the target of a government operation.

In one scene Kristen can be seen looking studious as she takes a phonecall from her boyfriend who, while working in a 7/11 - has just killed two police officers. 

The twist seems fitting given that movie database IMDB claim the project has been rated 'R' for 'strong bloody violence, language throughout, drug use and some sexual content'.

Hilariously, the tagline for it reads: 'There's nothing more dangerous than a stoned cold killer'.

Not typecast: Sporting a bloody mouth and cuts all over her face, she cut a bellicose character and played a very different persona to Twilight's Bella Swan...

In one gritty scene Kristen can be seen having a dramatic stand-off with military officials, who are determined to exterminate her love interest.

In fact, one of the recently-released film posters shows Kristen in character, smoking a cigarette while the smoke rises to form the name of the film.

Another sees her sat like a buddha bodhisattva, or Cundi - complete with several arms. 

But, rather than implements for enlightenment, Kristen's on-screen alter ego carries a loaded gun, a grenade, a cigarette and a bong to take on the establishment while under the influence.  

Wearing a pair of rolled-up jeans, tan leather boots and a crop top emblazoned with the film title, she was certainly on-message for the comedy-infused project.

Kristen's career has certainly done well in recent years - in 2014, she delivered critically acclaimed performances in Still Alice and in Clouds Of Sils Maria.

The actress even won France's coveted Cesar award for best supporting actress in the second movie.

She is, according to IMDB, also set to appear in a as-yet-untitled Woody Allen project which begins filming in 2016, plus Billy Lynn's Long Halftime Walk with Vin Diesel. 

Upset: The star suffered plenty of action shots in the film - complete with plenty of emotionally-charged scenes
