Goofs

At the end of a car chase, which is shot in broad daylight, the film cuts to a miniature of the car going off a model railroad-size road and steep embankment (with accompanying unnecessary sparking effects)and crashing at the bottom. The effect is shot taking place at night, despite the fact the preceding chase had just been on a sunlit day. When the scene cuts back from the model to a live scene of the actors investigating the wreck, it is also filmed as a night shot in order to match the previous miniature scene.

As Anton Fryd's vehicle pulls up there is another vehicle in the roadway which Fryd's vehicle pulls along side of, he gets out and his driver leaves. Moments later as the driver of this other vehicle flees, the vehicle has moved to the middle the roadway.

Cmdr. Mike Halstead (Tony Russel) and his partner look through a notebook supposedly containing a list of names of the victims, however the pages are clearly blank.

The space shots of the astronauts and space station are obviously done with wires. The wires noticeably swing back and forth, adding swaying motions to the objects that would not be present in reality. This is particularly egregious when the astronauts first exit their rocket's hatch in the opening sequence.

At roughly the 8-minute mark, an enormous hair appears in the lower right corner. As it only occurs in this one shot, it's clearly in the camera negative; either they didn't have time to reshoot the scene or felt it wasn't worth the bother.

At 21:00, A sign says "U.D.S.C.O." which stands for "United Democracies Space Command" however, nothing corresponds to the "O" in the name. A proper acronym would have been "UDESCO", instead of the erroneous initialism. Also, for some reason, the sub-name for the location on the plaque - System Headquarters - is enclosed in quotation marks.

Wires holding the astronauts up are visible during the beginning spacewalk. Most notably as the astronaut nears the space station ledge.
