I am – Hercules!!
From Wednesday’s Variety:

Willis will play Adam "Kane" Marcus, a mercenary who makes an unlikely alliance with a schizophrenic killer named James Lynch. The duo is forced on a mission to retrieve a stolen microchip. The vidgame has sold 2 million copies worldwide since its launch in November, 2007.

Willis (and "Bandits" co-star Billy Bob Thornton) have been rumored to be in the running for the project since November, but now we apparently have an actual contract drafted for Walter B's signature. Still no official word on Thornton. Longtime stunt coordinator Simon Crane directs from a screenplay by somebody named Kyle Ward for Lionsgate. I will rely on our gaming talkbackers to reveal whether or not the Willis character is the one on the left. Read all of Variety’s story on the matter here.
