introduction for Miles. While the film was being shot, Wanger tried to get permission in England to use a Winston Churchill quotation as a preface to the film. The producer sought out Orson Welles to voice the preface and a trailer for the film. He wrote speeches for Welles' opening on June 15, 1955, and worked to persuade Welles to do it, but was unsuccessful. Wanger considered science fiction author Ray Bradbury instead, but this did not happen, either. Mainwaring eventually wrote the voice-over narration himself. The studio scheduled three film previews on the last days of June and the first day of July 1955. According to Wanger's memos at the time, the previews were successful. Later reports by Mainwaring and Siegel, however, contradict this, claiming that audiences could not follow the film and laughed in the wrong places. In response the studio removed much of the film's humor, "humanity" and "quality," according to Wanger. He scheduled another preview in mid-August that also did not go well. In later interviews Siegel pointed out that it was studio policy not to mix humor with horror. Wanger saw the final cut in December 1955 and protested the use of the Superscope aspect ratio. Its use had been included in early plans for the film, but the first print was not made until December. Wanger felt that the film lost sharpness and detail. Siegel originally shot Invasion of the Body Snatchers in the 1.85:1 aspect ratio. Superscope was a post-production laboratory process designed to create an anamorphic print from non-anamorphic source material that would be projected at an aspect ratio of 2.00:1. Original intended ending Both Siegel and Mainwaring were satisfied with the film as shot. The original ending did not include the flashback framing, and ended with Miles screaming as truckloads of pods pass him on the road. The studio, wary of a pessimistic conclusion, insisted on adding a prologue and epilogue suggesting a more optimistic outcome to the story, leading to the flashback framing. In this version, the film begins with Bennell in custody in a hospital emergency ward, telling a consulting psychiatrist (Whit Bissell) his story. In the closing scenes, pods are discovered at a highway accident, confirming Bennell's warning, and the authorities are alerted, likely stopping the pod distribution and resolving the extraterrestrial threat. Mainwaring scripted this framing story and Siegel shot it on September 16, 1955, at the
