Chris Pratt is in talks to star in 'Cowboy Ninja Viking'.

The 'Guardians of the Galaxy' actor has entered into negotiations to take on the lead role in the action-adventure, according to Deadline.

The movie is based on a graphic novel of the same name by AJ Lieberman and artist Riley Rossmo which follows a deadly assassin with multiple personalities.

Although the director of the movie is yet to be announced, 'Zombieland' writer Everett David Reese has already penned a first draft of the script, with a second coming from Craig Mazin, writer of 'The Hangover Part II'.

Mark Gordon from the The Mark Gordon Company will produce the movie alongside Film 360's Guymon Casady and Ben Forkner.

Meanwhile, Chris will next appear in 'Jurassic World', the long-anticipated fourth instalment of the 'Jurassic Park' franchise.

The 35-year-old actor recently revealed that filming for the movie - due out in 2015 - is complete and insisted it will knock audiences' ''socks off''.

He said: ''It's going to knock your socks off. It's gonna be so awesome, so awesome. And to the long-time fans of the franchise, it's in good hands.''

The upcoming movie will feature many of the dinosaurs that appeared in the first 'Jurassic Park' film, as well as some that have never been seen before.

Bryce Dallas Howard, Vincent D'Onofrio and Omar Sy have all been cast in the film, which is scheduled to be released on June 12 next year.
