This is not a celebrity or public figure appearing "as himself" in an entirely fictional work. Those examples should go under As Himself. This is when events are being re-enacted by the person who enacted them in the first place.
If a starring role, may overlap with Non-Actor Vehicle. Compare Real Person Cameo. Contrast Character as Himself, in which a fictional character is given a real-world screen credit. Also contrast Adam Westing, where an actor plays his public persona.

Singer Pete Seeger also played himself.

Of course, the bulk of the film is spent on a minor bit of creative liberty suggesting he regained his passion for basketball by player-coaching the Looney Tunes to victory in a high-stakes match against alien slavers, but the parts that focus solely on Jordan play the trope quite straight. For an extra bit of Reality Subtext, the practice he got during the making of the film helped sharpen his skills for the very unretirement depicted in the film's final moments.
