Alien Intruder

Sharp-eyed viewers may think the Western town scenes look like the same town as the Dr. Quinn, Medicine Woman series. Indeed, it is the same Paramount Ranch town that depicted Colorado Springs for that series. The scenes for this movie were shot between the filming of the Dr. Quinn pilot and the return of the crew later in the year to film the one hour episodes. Some of the Dr. Quinn signage can be seen on some of the buildings. This was permitted because Dr. Quinn had not been seen on television. Productions that used the town later, while Dr. Quinn was at the ranch, were not allowed to show the Dr. Quinn signage in their shots.

At the start of the film, the USS Holly is shown spinning uncontrollably in space, but on board the ship the crew and all the loose objects are completely unaffected by the centrifugal force.
