Watch Christian Marclay’s 2010 film, The Clock, and you’ll need little convincing about its artistic merit. (If you haven’t seen it, read Ben Lerner’s 2014 masterpiece 10:04, which was inspired by the film and speaks to Marclay’s genius.) The Clock is a 24-hour montage pieced together from thousands of film and television scenes, each one containing a clock or another reference to time. When the film plays, its content syncs with the actual time of day—attend a screening of it at 10:04 P.M., for example, and you’ll see Marty McFly sent back to the future. Three years ago, Marclay released a stylistically related project, called Doors. It took him 10 years to create. As the title suggests, this collage features film clips of doors that open and close, slam and creak, welcome you in and send you out. Doors runs just under 60 minutes, but is every bit as engrossing as its maximalist predecessor. See it in Boston this summer. —Jack Sullivan
