Giannis Antetokounmpo Shoots Down Role In LeBron's 'Space Jam 2', I'll Pass

Giannis Antetokounmpo wants no part of a role in LeBron James' "Space Jam 2" ... saying he'd rather focus on basketball than his movie career.

"I don't like being Hollywood," Antetokounmpo told ESPN ... "I don't like all this extra drama. I am just going to try to be me."

Of course, LBJ is working on a sequel to the ultra-popular Michael Jordan flick ... and getting NBA studs for an on-screen battle with the Monstars is pretty necessary for the new movie.

But, Bron's reportedly having trouble locking up top-tier NBA talent for the roles ... and now, he'll have to move forward without the Greek Freak, one of the best players in the league.

According to ESPN, Giannis says he ain't down to give up 2 weeks of his summer training to join up with LBJ on the silver screen.

Which begs the question ... who will step up for Bron?

We know he's tight with Dwyane Wade, Carmelo Anthony and Chris Paul -- but those guys ain't exactly the young superstars taking over the NBA.

Guessing he's got names like Kevin Durant, Steph Curry, James Harden, Russell Westbrook, Kawhi Leonard and Anthony Davis on his wish list.

Jordan had Hall of Famers like Larry Bird, Charles Barkley and Patrick Ewing in his version of "Space Jam" ... and if LBJ can't at least somewhat match that cast, ya know the criticism will be flyin'!!!
