Trivia
Howerton was going to study Aerospace Engineering at Auburn University before deciding to attend Juilliard, where he graduated with a B.F.A. in the Actor Training Program. He is a fairly talented vocal mimic and acquits easily to impersonating various dialects, a skill he developed during his "military brat" childhood which require constant moving to different areas and countries.
