Oct 20, 1956: William Holden and other Hollywood presonalities attended the opening of the new base theater and viewed a screening of "Toward the Unknown," which was filmed on the base. (From Desert Wings, the Edwards AFB newspaper).

The film was to orginally been called "Flight Test Center." Apparently Larry Bell was not happy with the original screenplay when he read it. He was also asked to make an X-2 mock-up for the film. The DOD also asked for no less than 14 scenes to be rewritten before they would give permission to film at Edwards (Thanks Rob G.!).

Toward The Unknown is known as "soli nell'infinito" in Italy
