The Clock is 24-hour work of video art by artist Christian Marclay playing at the David Rubenstein Atrium at Lincoln Center through August 1. Marclay has miraculously brought together thousands of clips from the entire history of cinema, from silent films to the present, each featuring an exact time on a clock, on a watch, or in dialogue. The resulting collage tells the accurate time at any given moment, making it both a work of art and literally a working timepiece: a cinematic memento mori.

Marclay also composed the soundscape, driven by a racing and swelling symphony of ringing, ticking, footsteps, laughter, tears, and music.
