View Comments NBA legend LeBron James spends most of "Space Jam: A New Legacy" trapped in the "server-verse" of the Warner Bros. Studios computer system after being kidnapped by the unhinged villain Al G. Rhythm (Don Cheadle). These movie beats, for sure, are not based on James' real life. Even the bit where animated James turns into superhero Robin is fictional (James would so transform to Batman!). But the movie's at-home elements, such as at James' rocking mansion with that blue basketball court and his loving onscreen family, seem as if they could be real. Here's what's true and what's not true about James' life in "Space Jam" (in theaters and HBO Max).
