Continuity mistake: After they've destroyed the alien craft spotted flying around inside of the Belmont lab, Dr. Marvin and the others decide to pack up and leave. Even though the sound has been edited out, the car and truck are already running with their headlights on before anyone gets into them. (00:51:50)????
Continuity mistake: After they pull over to the side of the road and look at the UFO, Dr. Marvin gets back into the drivers seat and hands Carol a Chesterfield from his shirt pocket. In the previous shot he didn't have anything in his shirt pocket, in fact he didn't even have a pocket on his shirt. (00:06:00)????
Continuity mistake: Dr. Marvin and Major Huglin leave The Internal Security Commission meeting together and drive from The Pentagon to the doctor's hotel. Even though we just saw Carol and Dr. Marvin fly into Washington in an airplane he's driving the exact same make and model car that they were in at "Operation Sky Hook". Even the California license number AV-35-B7 is the same. (00:30:00)????
