"They’re here already! You’re next! You’re next, You’re next…! "
Both director Don Siegel and screenwriter Daniel Mainwaring were satisfied with the film as shot. It was originally intended to end with Miles screaming hysterically as truckloads of pods pass him by. The studio, wary of such a pessimistic conclusion, insisted on adding a prologue and epilogue to the movie that suggested a more optimistic outcome to the story which is thus told mainly in flashback. In this version the movie begins with a ranting Bennell kept in custody in a hospital emergency ward. He then tells an arriving doctor (Whit Bissell) his story. In the closing scene, pods are discovered at a highway accident, thus confirming his warning. The Federal Bureau of Investigation is notified, though it is left ambiguous whether they intervene in time to save the Earth.
Mainwaring scripted this framing story and Siegel shot it on September 16, 1955, at the Allied Artists studio. In a later interview Siegel complained, “The film was nearly ruined by those in charge at Allied Artists who added a preface and ending that I don’t like.” In his autobiography, Siegel added that “Wanger was very much against this, as was I. However, he begged me to shoot it to protect the film, and I reluctantly consented.”
