This film sits firmly in the "McConaissance" era, and Matthew McConaughey is magnetic as the titular character.

A desperate young man (Emile Hirsch) hires a contract killer, who also happens to be a police detective ("Killer" Joe Cooper, played by Matthew McConaughey), to murder his mother for her insurance money. When he can't pay the fee upfront, Joe takes the sister (Juno Temple) as "collateral."

The string is a "release tag" used by digital preservationists to describe the exact specifications of the video file: Killer Joe (2011)
