Few actors have had as diverse a career as Billy Bob Thornton. Since breaking out in the 90s, hes demonstrated a knack for playing gruff curmudgeons with a heart, and hes one of the rare actors who can effortlessly pull off drama and comedy equally well. Films like Monsters Ball showcase his ability to beautifully project internalized emotion, the Fargo miniseries proved that he could be genuinely terrifying, and Bad Santa showed him at his most laugh-out-loud funny.
