Fast cutting is a film editing technique which refers to several consecutive shots of a brief duration (e.g. 3 seconds or less).One famous example of fast cutting is the shower scene in Alfred Hitchcock's film Psycho (1960).[2] The film Mind Game makes extensive use of fast cutting to convey hundreds of short scenes in the space of fifteen minutes.[3] The technique is derived from the hip hop culture of the 1990s and jump cuts first pioneered in the French new wave.The work of Edgar Wright, most notably in his collaboration with Simon Pegg (Spaced, Shaun of the Dead, Hot Fuzz, and The World's End) uses the technique for comedic effect.
