Christian Slater, Adewale Akinnuoye-Agbaje, and Holt McCallany have all joined the cast of the Untitled Sylvester Stallone/Walter Hill Project, formerly known as Headshot.

Sylvester Stallone stars as a hitman who must team up with a New York City cop (Sung Kang) to take down a common enemy. Adewale Akinnuoye-Agbaje will play the man they are both after, a powerful attorney who has covered up a scam to exploit poor neighborhoods in New Orleans. Holt McCallany is locked in as a dirty cop who eventually strays from the right side of the force, while Christian Slater will play a middleman of sorts.

The screenplay by Alessandro Camon is based on the popular graphic novel Bullet to the Head, by Matz and Colin Wilson. The Untitled Sylvester Stallone/Walter Hill Project will head into production later this summer.
