Down (re-titled The Shaft on US releases) is a 2001 science fiction horror film written and directed by Dick Maas and starring James Marshall, Naomi Watts, and Eric Thal. It is a remake of the 1983 Dutch-language film De Lift, which was also directed by Maas.

Watts plays the role of pushy journalist Jennifer Evans, and Marshall is Mark, an elevator repairman and former Marine. The movie was mainly filmed in the Netherlands, although the crew briefly visited New York City and the District of Columbia as well for exterior shots.

The film was funded by Nederlands Fonds, and produced by First Floor Features and AVRO, with post-production by Sapex Scripts. It premiered at the Cannes Film Festival in May 2001, and was released direct to video in the United States two years later.
