in filming because of a bad camera cable. There was a further delay from 11:05 am to 11:25 am to allow water to drain so a crane could be used properly. These scenes involved nine-hour workdays. When the actors were not filming, they were sent to have publicity shots taken. The film was originally shot in the standard 4:3 aspect ratio, but midway through filming, on June 22, it was decided that the remaining footage would be shot in 1.75:1. The belief was this would give the film a better look, as a shorter frame would allow the production department to scale down the height of certain props for the special effects. During this period, Grant Williams suffered the first of many injuries on set. On June 22, he reported to the studio hospital with a scratched leg; on June 29, he had to leave the set to be treated for an eye condition; and on July 2 he both had to be driven to the hospital for further treatment for his eyes and was sent to the studio hospital with blisters and scratches from climbing sets. Due to Williams' injuries and some special effects shots being too bright, the film was four days behind schedule and $25,000 over budget. Post-production Special effects shots using black velvet trick photography took three weeks of post-production and were scheduled after the film completed production on July 13, 1956. Warren described the special effects as "hard to assign correctly." Clifford Stine, whose field was process work and rear screen projection, is credited with "special photography". The boat scene at the beginning of the film was shot on Universal's process stage, which allowed for rear screen projection. Shots of Scott in certain scenes, such as his encounter with the mist, were shot with him against a black velvet back drop. According to Randy Stuart, the film's ending had Williams return to his original size, which Matheson felt was the wrong ending for the story. Arnold argued with Universal over the ending. The studio wanted a happy ending, while he wanted the original ending that had been shot. To decide on which ending to use, a test screening was held to judge the audience's reaction. Lucas said audience review cards from a December 7 preview screening in California included comments reacting to the ending such as: "Should've had a different ending, should've grown again." and
