Overacting (also referred to as hamming or mugging) is the exaggeration of gestures and speech when acting. It may be unintentional, particularly in the case of a bad actor, or be required for the role. For the latter, it is commonly used in comical situations or to stress the evil characteristics of a villain. Since the perception of acting quality differs between people the extent of overacting can be subjective.

Unter Overacting (englisch für: „Überspielen“) bezeichnet man in der Schauspielkunst den übertriebenen Einsatz nonverbaler Ausdrucksmittel wie Gesten, Gebärden, Mimik und Miene.
