Lance LeGault served as a double and stand-in for Presley's dual roles.
General Alvin Donford:
Strategic Air Command Logistics considers Big Smoky Mountain the most important site in this group of ICBM missile bases. One that we feel will be vital.
Early in the film the Captain Salbo character wears a tropical Army Class A uniform, without decorations; decorations are mandatory on this uniform, especially with his service record described in the dialogue. Elvis' lieutenant character also wears Air Force service dress (Combo 1) with pilot wings but no decorations. USAF officers in 1964 would have at least the National Defense Service Medal. Also, military creases are not allowed in USAF uniform shirts, as Elvis' character wore.
At the end of the movie, the "THE END" sign is shown by Pappy Tatum (Arthur O'Connell) and Captain Salbo (Jack Albertson) as they each hold up a paddle, one reading THE, and the other reading END as they both shake hands.
