Bandits (2001)

Bandits is a crime comedy starring Bruce Willis and Billy Bob Thornton as two mismatched bank robbers whose carefully choreographed routine attracts both media attention and law enforcement. Blending character-driven humor with a series of low-key heists, the film focuses more on personality clashes and romantic complications than escalating action. Cate Blanchett adds an offbeat romantic angle that shifts the story away from traditional crime tension.
