Trivia

The interior B17 scenes in the film's opening scene were shot in "Texas Raiders," a B17G bomber which the production team flew for several hours as they needed in-flight footage to match the continuity of the scene. Texas Raiders crashed in Houston a year later, making "Condor's Nest" the final film in which the airplane appears.

The shot of the Nazi flag unfurling over the Pacific coast of South America was a last-second decision after director Blattenberger grabbed the flag out of the prop box on a whim as the crew left for the airport. The crew spent two days location scouting and drove hours into the sand dunes of Paracas, Peru, to achieve that shot.

Arnold Vosloo, James Urbaniak and Bruce Davison, who didn't speak a word of German prior to accepting their roles as Germans, learned the entire farcical archaeological discussion in German.

The production's art department spent over a year building the crashed B17 bomber featured in the opening scene of the film. The plane was engineered in conjunction with historians, aviation enthusiasts, and the producers themselves, and carefully constructed in a field in eastern North Carolina with over 30,000 rivets.

The fuselage and wings are made of plywood, framing lumber, and low-grade industrial aluminum, but the cockpit housing, engine cowls, nose canopy, and bent propellers are original parts salvaged from wrecked B17s.

The airplane's top turret and fiberglass propellers were originally built for and featured in war movie MEMPHIS BELLE (1990).

The Buenos Aires bar in which Jorge Garcia performs as its proprietor is the same bar that features in Sony 's "Point Man" (2019) where it was a GI bar in 1960s Saigon. The crimson bull from the original set is visible in the background, but with the words changed from Vietnamese to Spanish.
