4. Mel Gibson

If the first name on this list surprised you, it really shouldn’t. Mel Gibson was the first name Ryan Reynolds/Deadpool mentioned in the post-credits scene.

Oh! I can tell you one thing, and it's a bit of a secret. The sequel? We're gonna have Cable. Amazing character. Bionic arm, time travel! We have no idea who we're going to cast yet, but it could be anyone. Just need a big guy with a flat top. Mel Gibson, Dolph Lundgren, Keira Knightley? She's got range "“ who knows? Big secret, shhh.

Mel Gibson bulked up for Expendables 3, so we can already see that he qualifies as physically imposing. He’s done numerous action flicks, notably the Lethal Weapon series and the first three Mad Max films. From a physical standpoint and acting criteria, Gibson could pull it off, though it ain’t easy to imagine him with a bionic eye and metal arm.

However, considering the controversies plaguing him for the past decade, it’s safe to say Gibson is not anyone’s favorite.
