Jonah Hill in ‘Superbad’
With his cargo shorts and white-boy ‘fro, Jonah Hill’s Seth actually made for a pretty convincing 18-year-old in the 2007 hit “Superbad.” It might surprise you to learn that Hill was already 23 at the time, just one year younger than Seth Rogen and almost six years older than “McLovin” actor Christopher Mintz-Plasse. Maybe he’s the one who should have had the fake ID!
