Other mistake: The protagonist is reading the booklet illustrating the wonders of his home. Something strange about it; the paragraph by the title "State of the art lift system", with a big lift icon to the side, has merely the first couple of lines talking about lifts, and then moves on, without any transition, to the subject of pets, adoption and all related matters.

Other mistake: If you look closely after the film leaps ahead a year, Reed's file on Ben lists his birthdate as 1986, but the prologue of the film which features Ben and Reed at roughly 10 years old each is set in 2007. The math doesn't add up.
Other mistake: After Dr. Palmer and his friend Ryan have placed the miniature horses in the back of his truck, he drives off. After this, a robot runs past Ryan chasing after Dr. Palmer. The robot takes a shortcut through a forest and then leaps off a very tall cliff, but somehow Dr. Palmer's truck is directly below, driving at the bottom of the cliff, despite only driving off a couple of seconds ago.

Other mistake: To prove his point to his wife, Mike searches a database for a certain date. It's the date of their son's birthday. Cage says "on July 15", but if you look at the screen, the search is for "past 6 years, April 27." It's a double mistake, since he then does another search, which produces different results...but on screen, the date is always the same one. (00:45:30)
Other mistake: Captain Forsyth is looking at the dossier about The Gourmet Detective; the interrogation happens in the evening with everyone still dressed for the formal dinner, but the file was printed at 9 AM. There's no reason why the police would have printed that file at that time of the day. (00:23:15)
Other mistake: Whilst the main character is having a 'talk' with the general, the world clocks on the way show 3:50 on time 1, and 3:49 on time 2. (01:25:10)
Other mistake: During the opening, when Danny rides his bike past the boatyard, the image has been reversed. The registration numbers on the boats appear as mirror images.
