There is a thin line between being admirably ambitious and being intolerably mercenary, but in the leading awards-season contender Marty Supreme, Timothée Chalamet shows himself determined to dance atop that tightrope. 

This constitutes an act of substantial actorly bravery on the part of Chalamet, who, along with the acting chops he demonstrated in Call Me by Your Name and A Complete Unknown, seems to have been born with a genetic predisposition for obnoxious self-promotion that is unique even for his attention-grabbing profession. This makes his performance in the new movie, on which he also served as a producer, revealing if not outright autobiographical.
