Vincent D’Onofrio, known for his intense dedication to roles, transformed dramatically for Stanley Kubrick’s Full Metal Jacket at age 24—gaining 80 pounds and shaving his head to play the troubled Leonard. The physical change earned critical praise but took a toll on his self-image and how others perceived him.

The Brooklyn-born actor began on stage and worked odd jobs before his breakout role, which he credits for launching his decades-long career, including Law & Order: Criminal Intent, Daredevil, and Jurassic World.
