Autobiographical Role

When someone plays himself in a Docu Drama, Biopic, or other Dramatization of a true story.

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.
