Is LeBron James, who plays a fictionalized version of himself, the best actor? No, and there's even a joke in the film about how athletes in movies is a terrible idea. Despite having an awkward start, James is absolute magic once he's sucked into the serververse by Don Cheadle's Al-G. Then there's his chemistry with costars Cedric Joe, who plays his son, Dom, and Sonequa Martin-Green, who plays his wife, Kamiyah. A big fan of 1996's Space Jam, Martin-Green shared with POPSUGAR the difficulties of playing a fictionalized version of a real person. "That was a little bit of a mind trip," she said with a laugh. "So, LeBron is playing himself, but he's also this sort of alternate version of himself. When I was creating my life as Kamiyah, I had to do a blend of some things that really happened to him and Savannah [James], but then also things that are just particular to the story."
