Several of the filmmakers are heard but not seen in the film. The man yelling "Oh my God!" repeatedly when the head of the Statue of Liberty lands in the street is producer Bryan Burk, and director Matt Reeves voiced the whispered radio broadcast at the end of the credits. After viewing a cut of the film, Steven Spielberg suggested giving the audience a hint at the fate of the monster during the climax, which resulted in the addition of a countdown overheard on the helicopter's radio and the sounding of air raid sirens to signal the forthcoming Hammer Down bombing.
