• Before making a single edit, Tropedia EXPECTS our site policy and manual of style to be followed. Failure to do so may result in deletion of contributions and blocks of users who refuse to learn to do so. Our policies can be reviewed here.
  • All images MUST now have proper attribution, those who neglect to assign at least the "fair use" licensing to an image may have it deleted. All new pages should use the preloadable templates feature on the edit page to add the appropriate basic page markup. Pages that don't do this will be subject to deletion, with or without explanation.
  • All new trope pages will be made with the "Trope Workshop" found on the "Troper Tools" menu and worked on until they have at least three examples. The Trope workshop specific templates can then be removed and it will be regarded as a regular trope page after being moved to the Main namespace. THIS SHOULD BE WORKING NOW, REPORT ANY ISSUES TO Janna2000, SelfCloak or RRabbit42. DON'T MAKE PAGES MANUALLY UNLESS A TEMPLATE IS BROKEN, AND REPORT IT THAT IS THE CASE. PAGES WILL BE DELETED OTHERWISE IF THEY ARE MISSING BASIC MARKUP.

Many proudly proclaim that they are impartial to the use of Special Effects in a movie, and value more that the movie have a brain (and presumably also a heart, lungs, stomach, and other major organs, but lets not go there or the metaphor might spleen away). But we all know the truth: Special Effects can make or break a movie faster than a Serial Killer can cut the Plucky Comic Relief in two with a machete in a shower of High-Pressure Blood.

So, here are some of the ways movies fool us (or don't) with the Spectacle of fiction.

Special Effects can be classed into subgroups depending on how they were acheived:

Gathered here are some cool and corny special effects, for your reading pleasure.


  • In old black and white films, chocolate syrup was used to simulate blood. Its dark color and viscosity made for pretty convincing texture.
    • For color films, Karo-brand sugar syrup plus red food coloring became the standard, and is still used today.

Camera Effects

  • With older, non-digital cameras, using a black screen or cover so that only part of the film is exposed (and thus the rest can have something else filmed onto it).
  • A dark cover could be used to simulate night-time while shooting in daytime. Unfortunately it does nothing to eliminate shadows caused by sunlight, leading to the slightly hilarious effect of having obvious sun-shadow at night.
  • A filmmaker could create a "ghost" by exposing the film to the same scene twice, once with and once without the actor.
  • The Rotoscope is a device which projects film images downward onto a table, where the image can be traced by hand. Although the Rotoscope machine has been superceded by Photoshop-type software, the techniques remain largely the same.
    • By tracing the outline of an object in the frame, a custom-shaped traveling matte can be created. This is how the (models of) Imperial Walkers in Return Of The Jedi were able to walk behind (real) trees.
    • A less common usage is to actually trace the entire film image, creating a completely hand-drawn frame. Ralph Bakshi's adaptation of The Lord of the Rings used this technique, and it was also used for spaceship shots in the 70s/80s Flash Gordon cartoon.
    • Chroma Key (more commonly known as green/blue screen) is an evolution of the same concept. Only by using a vibrant and bright color the computer can automatically know where to rotoscope for you.

Environmental Effects

  • Backlighting is used for rain scenes, as rain doesn't show on camera otherwise.
    • Indeed, that famous scene in Singin in The Rain where Gene Kelly dances in the rain? That rain was milk mixed with water so it would show up on camera.
