Fan Casting Lobo (2035)

There's a billion dollar bounty on someone's head in a far off system at the end of the universe. While not knowing much about it, the Main Man knows he's gonna obliterate this bastich, get his cash, and do god knows what with it. But, he has some distance between him and the bounty, and a whole lot of other hunters after it as well. Who's gonna get there first? [Author's Note: I'm aware that these actors would be too old for their respected roles. I would be casting these movies if they were to happen today even though it's for much later. It's very unrealistic, but that's how I'm doing it.]
