J.K. Simmons is the big-screen equivalent to that sarcastic uncle who shows up at family gatherings and makes (often hilariously) snarky comments about everyone and everything. Always a welcome addition to any Hollywood comedy, the 57-year-old actor makes the most of his usually limited screen time, either offering sage yet blunt advice (see: Juno), tearing main characters new assholes (as Daily Bugle publisher J. Jonah Jameson in Sam Raimis' Spider-Man movies), or dropping playfully dismissive one-liners (Extract).

For the most part, Simmons gets called upon to play bosses or father figures, and it's rather obvious why that's the case: Nobody makes authority figures seem like seasoned wisecrackers (think George Carlin) quite like J.K. Simmons.
