Other mistake: Guy goes to the closet and gets Hutch's coat as he's about to leave after having coffee with Rosemary. If you look at her she looks ghostly as they applied more makeup to her face between shots. Unfortunately they missed some spots around her eyes and on her forehead. (01:06:50)
Other mistake: Taylor believes he is on a planet 300 light-years from earth for most of the movie. However, after spending months there, he would have seen the moon at night a number of times, letting him know where he really was before seeing the Statue of Liberty.
Suggested correction: Not necessarily; any astronaut knows that many, many planets have moons, so Taylor could have easily thought that it was simply an odd coincidence that the "other" planet's moon closely resembled Earth's moon.
Other mistake: Mrs. Petrie, Dr. Flemming's secretary, makes two phone calls to Joan Hudson. She dials seven numbers for the first call but only six numbers for the second call.
