10. The Wolf of Wall Street (2013) – Actor

Reiner delivered one of his sharpest late-career performances as Max Belfort, the blunt, foul-mouthed father of Leonardo DiCaprio’s fraudulent stockbroker Jordan Belfort. Directed by Martin Scorsese, the film based on Jordan's scarcely believable life became a modern classic. Reiner’s scenes provided both comic relief and moral grounding, proving his enduring presence as a character actor.
