Christian Marclay’s The Clock is a cinematic tour de force that unfolds on the screen in real time through thousands of film excerpts that form a 24-hour montage. Appropriated from the last 100 years of cinema’s rich history, the film clips chronicle the hours and minutes of the 24-hour period, often by displaying a watch or clock. The Clock incorporates scenes of everything from car chases and board rooms to emergency wards, bank heists, trysts, and high-noon shootouts.

The Clock was preceded by similar works and Marclay also created a piece entitlesd Telephones (1995)
