Special Effects
From Hash, Inc. WIKI
Numerous Special Effects are required in a movie such as Tin Woodman of Oz.
Fluids, Rain and Water Effects
The goal of any good effect is to contribute in significant ways but not take the audience out of the movie. Care was taken to to enhance the environment, the mood, the weather and other factors contributing to each scene. When you empathize with a character distracted without being drawn out of the story the effects have accomplished their goal.
