Other mistake: When David and Jennifer are sat at the IMSAI terminal making the flight reservation for Paris, the date on the booking system shows as 18th March 1982, but the date of the flight is 18th August 1983. (00:29:11)
Other mistake: When Jennifer meets David in Oregon she says she drove 3 hours to get there. In the next scene they are getting off a bus to catch the ferry. What happened to her car?
Suggested correction: There are possibilities off-screen as to why. It's possible that the bus used its own private road to get to the ferry which may be closed to the public, or the parking lot may have been too expensive and they parked on a street instead and caught a bus. It's not really known, but those are some possibilities.
Other mistake: On the DVD cover, Broderick's and Sheedy's faces and the reflection of their faces on the computer monitor don't match.
Other mistake: When David and his dad are sitting at the dining table, dad butters his bread to roll his corn on the cob. You can see that the butter melts on the corn and bread, but then he bites into the corn and finds that it is raw. Raw means uncooked and the cob would be cold, therefore the butter wouldn't melt.
Other mistake: When Matthew Broderick is playing Galaga in the arcade, the game ends when he still has 2 lives left.
Other mistake: Why didn't Falken just call NORAD instead of going 1400 miles? NORAD in Colorado Springs, Colorado, U.S. to Goose Island, Oregon is far (1,388.5 mi). Robinson R22 has a maximum speed of approximately 115 miles per hour. The R22 typically has a maximum range of around 200 to 240 nautical miles with standard fuel tanks. It would have to refuel 8 times, making that long 16+ hour trip before the wargame ended, is impossible (not to mention arriving 'just in time').
Other mistake: When David was having his computer dial all the numbers in Sunnyvale, he pulled up the list of numbers already dialled, and there are numbers with the prefix '936', but before he pulled up the list, when the computer was dialling the numbers, the 936 prefix was on the far right hand side. No numbers with the 936 prefix were dialled yet, so they could not have been on the list.
Other mistake: When David first logs into the system after finding the right password, it shows a phone # beginning with the prefix 936. The only problem was that earlier when his computer was dialing numbers, he had not gotten to 936 yet. That was the 4th prefix and he only got through the first 3. There is no way he could have dialed that number with his computer program.
