Corrected entry: When Max Walker (1994) and his wife Melissa are hanging on the edge of roof, one of McComb's thugs is crushing Walker's hand with his shoe. Then Walker from 2004 shoots the thug. You can see his dead body falling from the roof. He should hit the ground with his back, and his legs should be opposite the door. But, when Melissa goes down and walks near that body, it's lying on its stomach with its head opposite the door.
Corrected entry: Near the end of the movie, when 2004 Walker returns to the present, he sees that the sign 'Parker Datalink Systems' is restored and the one stating 'McComb Datalink Systems' is gone. Hard to believe, since the 2004 McComb had killed his old partner, 1994 Parker, the day before the sequence of events took place that restored the timeline of Walker and his wife. Unless the business miraculously stayed in the Parker family after the death of the patriarch. (01:29:35)
Corrected entry: At the beginning, the black guy stands in front of the panel and states that time travel has been invented and must now be policed. Instead of spending money setting up the TEC, training recruits etc, surely it would have been quicker and easier to seize the prototype of the time machine from the inventor. Assuming he only made one, this would then prevent any other time travel occurring.
Corrected entry: Unfortunately McComb hadn't grasped the concept of timeloops. The 2004 McComb says that even if he dies the 1994 version will still become president, however, based on the theories used in time travel films the 2004 McComb would always be destined to die in that house therefore never becoming president. That sequence was played out twice in the film anyway which adds weight to the theory.
Corrected entry: When Jean-Claude is explaining the dangers of time travel to the rookie, he points out to red stains on the back wall made by a previous time-car crashing against it. Why on earth would they have a wall there at all if there was any risk of people crashing into it? Why not have an equally long runway after the travel point for people to slow down on?
Corrected entry: In the beginning of the movie, while showing Walker's partner Atwood comparing the October 30, 1929 paper with the October 30, 2004 USA Today, Atwood circles Mid States Oil. The problem with this is the fact that October 30, 2004 falls on a Saturday, and USA Today does not print a Saturday paper. Instead, on Friday, it publishes a paper for the entire weekend, and it states Friday, Saturday, and Sunday on it.
