Thunder is a 1982 Japanese experimental short film directed by Takashi Ito.

Shot on 16 mm film,[1] Thunder makes use of long-exposure photography.

[3][4] Thunder features a series of photographic slides of a woman repeatedly covering and uncovering her face with her hands, projected onto the interiors of an empty office building.

The effect of the ribbon of light was produced using long-exposure photography, created frame-by-frame by a person with a flashlight moving throughout the building's rooms during long single-frame exposures.

[2][5] Thunder screened as part of the 34th Berlin International Film Festival in 1984, and was later shown at the Ishikawa Prefectural Museum of Art in 1996.
