New details have emerged on Walter Hill's upcoming action flick Headshot starring Sylvester Stallone and Thomas Jane.  As we previously reported, the story centers on a hitman (Stallone) and an NYPD detective (Jane) who team up to exact revenge.  According to What's Playing, the film will be, much like Stallone's The Expendables, a throwback to 80s buddy action flicks.  Hill reportedly signed on for the flick because it reminded him of the films he used to make like 48 Hrs. and Red Heat.  WP also says that Hill has fine-tuned Alessandro Camon's script and improved the "cool" dialogue and central relationship between Stallone and Jane's characters.I desperately hope that this film is better than Expendables and having Hill behind the camera gives me that hope.  However, it's interesting/sad that ever since 2006's Rocky Balboa, Stallone has essentially acknowledged that he's a relic and that the only way his stardom can continue is if he can transport audiences back to when he was actually a star.
