Jake LaMotta (Raging Bull)

If Jake LaMotta from 'Raging Bull' isn't at the top of your De Niro list, do you even know movies? Here's a guy who doesn’t just throw punches; he swings with emotional chaos that’ll knock your socks off! Watching him is like being in a thrilling but slightly dysfunctional relationship. Every scene is an intense back-and-forth, and just when you think you've got him figured out, bam! He hits you with another Oscar-worthy scowl. It's exhausting, compelling, and why we can't stop watching or arguing about it. Seriously, pick a side already!
