Deadline is reporting that Jackie Chan, Wesley Snipes, Nicolas Cage and Milla Jovovich are in various stages of talks to join The Expendables 3. The source of this story is apparently Lionsgate CEO himself, Jon Feltheimer.
Whilst Snipes, Chan and Cage have all been discussed previously, Milla Jovovich has come a little from left field. Stallone has previously said he was looking to get a young Sigourney Weaver type character for the franchise, so Jovovich would make sense in that regard.
Expect to hear more on this as it becomes available.
