Yep, though the original said "Superman", "Gandalf", "King Kong", and "The Iron Giant". So not too far off from the joke.

Within context of this film, I think it actually showcases just how little LeBron truly synergized with the Looney Tunes. Like the man had no care for the Tunes aside from helping him find his son. He only saw them as a means to an end, and didn't care about how they did their thing as long as it was "his way".
Compare that to Michael Jordon, who had a good synergy going with the Tunes and has enjoyed their company. Even when the Tunes kidnapped him to help themselves, Jordon agreed to at least practice with them and eventually risked his own freedom to keep the Tunes safe.
