This might be “Cameras in Movies, Part n+6” but it tags on an earlier post. Waay back in 2011, I did a report on the Stereo Realist, made by David White Co., 1947-1971 ( http://www.photo.net/classic-cameras-forum/00YCII ). As a sort of Easter Egg, I mentioned that the Stereo Realist was the camera used in the movie Them!  by Dr. Pat Medford (an entomologist with the Department of Agriculture, working with her father, Dr. Harold Medford the “foremost myrmecologist”). Them! is arguably the first, and certainly the best, of the “Big Bug” movies of the 1950s. It was originally meant to have been a 3D color film, but the craze was dying, so it was shot at the last minute in B&W mono, although a number of ‘stereo’ cliches of things coming at you in the picture were filmed. I have seen it stated that there actually was a second camera, but the film from it is not known to have survived. A tragic loss to those of us who love both stereo and big bugs. Here is Dr. Pat Medford (Joan Weldon) taking a picture of the giant ants’ “egg chamber” with the Stereo Realist. With her are the lead of the film, James Whitmore (as Sergeant Ben Peterson of the New Mexico police), and James Arness as the FBI agent Robert Graham. John Wayne is said to have seen Arness in this film, and from that recommended him for the role of Matt Dillon in Gunsmoke, Arness’s signature role (after the Thing , of course). [Disney supposedly found Fess Parker from a small role in this film, and there is a brief appearance by Leonard Nimoy].
