The theatrical form made famous by Marcel Marceau is known as

Silent film refers to a genre of film that was prevalent before the advent of synchronized sound. While silent films utilized visual storytelling similar to pantomime, they differ fundamentally as they incorporate captured motion and often include intertitles for dialogue, making them a distinct cinematic form rather than a live performance art.

Charades is a game in which players act out words or phrases without speaking, relying on the guesses of others for interaction. Though similar in using non-verbal communication, charades is primarily a recreational activity rather than a structured theatrical form with a defined narrative and artistic expression, as seen in pantomime.

Puppetry involves the manipulation of puppets to tell stories, often accompanied by dialogue. Unlike pantomime, which emphasizes human physicality and expression, puppetry focuses on inanimate characters and typically involves a voice or script, thus creating a different artistic experience.

Improvisation is a performance technique where actors create scenes and dialogue spontaneously. While it can be a component of pantomime, improvisation is not a distinct theatrical form and does not specifically relate to the silent, expressive nature that defines Marcel Marceau's work in pantomime.
