6. Keanu Reeves

This gun slinging maverick is no stranger to the action world and has proven himself several times over humanity's savior.

In his most memorable film, The Matrix, Keanu Reeves sacrifices his own life to cease the war threatening humanity's extinction.  Jim Raynor fortunately never had to make such a sacrifice, but on several occasions displayed his willingness to put his life at risk for others.

Such a skill is not easily taught and would prove invaluable in Reeves portrayal as Raynor. Keanue Reeves is also well versed in several pistols which would ideally copy the manner in which Raynor wields his trusty revolver.
