An extended look at “The Killer Inside Me” has come out in the form of a promo trailer. Almost six minutes in running time, the sneak peek unravels what this drama thriller is all about and gives out a look at Casey Affleck, Jessica Alba and Kate Hudson in characters.

In the movie set in the 1950s, Affleck stars as Lou Ford, a West Texas deputy sheriff who spirals downward. Starting as a bored small-town cop, he slowly turns into a ruthless, sociopathic murderer trying to cement his innocence when the evidence looks suspicious. Alba and Hudson, in the meantime, portray a prostitute and Lou’s girlfriend respectively.
