Efraim Diveroli – War Dogs (2016)

Played by: Jonah Hill

Speaking of whiny characters, Efraim Diveroli is so annoying that he makes watching War Dogs an honest challenge. He's a crass, overconfident, cash-hungry slob with a squeaky laugh that is arguably the most aggravating noise ever emitted by a human being. To give credit where it's due, Jonah is phenomenal in the role, and it's because of his skill that Efraim is (unfortunately) so unforgettable. Golden Globe nomination well earned, Jonah.
