Matthew Fox in first 'Alex Cross' pictures

The first images of Matthew Fox in Alex Cross have emerged.

The former Lost actor has transformed himself physically in order to play the role of Picasso, a cage fighter and assassin.

The film, which is adapted from a series of novels by James Patterson, follows detective Alex Cross (Tyler Perry) on a revenge mission after Picasso's murder of his wife.

Rob Cohen (The Fast and the Furious) directed the film from a script by Marc Moss and Kerry Williamson.

Moss previously worked on the script for 2001 Alex Cross adaptation Along Came a Spider, in which Morgan Freeman played the title role.

Fox was recently charged with DUI following an arrest in Oregon, and was accused of assaulting a bus driver last year.

Alex Cross will arrive in US cinemas on October 26, with a UK release date yet to be confirmed.
