Wet-for-dry is a term in the film industry for a special effect wherein an actor or prop is filmed in a water-filled tank, then imposed onto the film most often via Chroma Key or similar technology. The purpose of this is either to facilitate Slow Motion or to create the image of a supernatural creature not entirely bound by gravity. Filming in water works most effectively on hair and other long, flexible appendages, so expect this effect to take full advantage of such.


The opposite of wet-for-dry is dry-for-wet, where a subject filmed on a stage is imposed onto a water backdrop to avoid having to film underwater, thus making it possible for actors to do a scene while also being able to, for instance, breathe.

Examples of Wet-For-Dry:

  • Clouds (by means of dye solutions) were frequently done this way before CGI, though in a sense it's all still wet.


  • The dance of the Delphi in 300.
  • The Dementors in the Harry Potter films. Also, in the Half-Blood Prince film, actress Georgina Leonidas (who played curse-victim Katie Bell) was filmed wet-for-dry for the scene in which she is suspended in the air, so that her hair would look like it was flaring around her head.
  • The Ghost of Christmas Past in The Muppet Christmas Carol.
  • The spirits that come out of the Ark in Raiders of the Lost Ark were filmed in a tank to get a ghostly flowing effect on their hair and clothes.

Examples of Dry-For-Wet:

  • One of the oldest examples is 20,000 Leagues Under the Sea. There are scenes with actual divers, yes, but other scenes requiring James Mason and Paul Lukas to be seen through the helmets were accomplished this way.
  • Exterior shots of the underwater Aquatica facility in Deep Blue Sea were shot on a smoked-up soundstage, which bubbles added digitally.
  • For Your Eyes Only: Many of the underwater scenes (including the close-ups between James Bond and Melina) were filmed on a dry sound stage and had lighting effects, slow-motion photography, wind, and bubbles added in post-production. Actress Carole Bouquet (Melina) had a preexisting health condition that prevented her from filming underwater.
  • Nearly all the underwater scenes in the film version of The Hunt for Red October were actually done with models in a tank filled with air and smoke, because the smoke created the "just murky enough" effect the director wanted.
    • Same thing was done in The Abyss.
  • The scene in Lara Croft: Tomb Raider: The Cradle of Life in which Lara and her two companions travel down to the underwater Luna temple on motorised sleds was shot dry-for-wet on a smoked-up soundstage.
  • Sam's near-drowning scene at the end of The Lord of the Rings: The Fellowship of the Ring. Also, the drowned ghosts in The Two Towers, those which weren't CGI.
  • The underwater scene in The Spirit was filmed dry.

  • A rare theme park example: Tokyo Disney Sea's 20,000 Leagues Under the Sea ride achieves the illusion of traveling underwater by use of a suspended ride system through dry sets and vehicles featuring two-paned windows that contain water that bubbles as the sub pods "dive".
