Lucasfilm's Industrial Light & Magic (ILM) created the visual effects sequences. The script called for Willow to restore Fin Raziel (Patricia Hayes) from a goat to her human form. Willow recites what he thinks is the appropriate spell, but turns the goat into an ostrich, a peacock, a tortoise and, finally, a tiger, before returning her to normal. ILM supervisor Dennis Muren considered using stop motion animation for the scene. He also explained that another traditional and practical way in the late 1980s to execute this sequence would have been through the use of an optical dissolve with cutaways at various stages. Muren found both stop motion and optical effects to be too technically challenging and decided that the transformation scene would be a perfect opportunity for ILM to create advances with digital morphing technology. He proposed filming each animal, and the actress doubling for Hayes, and then feeding the images into a computer program developed by Doug Smythe. The program would then create a smooth transition from one stage to another before outputting the result back onto film. Smythe began development of the necessary software in September 1987. By March 1988, Muren and fellow designer David Allen achieved what would represent a breakthrough for computer-generated imagery (CGI). The techniques developed for the sequence were later utilized by ILM for Indiana Jones and the Last Crusade, Terminator 2: Judgment Day, and Star Trek VI: The Undiscovered Country.
