Continuity mistake: When Jennifer comes into work the next day after her dinner date with Dick, her face is covered in hives from an allergic reaction. Later when Dick interrupts her choral group, the hives on her face have disappeared. She and Dick are wearing the same clothes in both scenes, so she couldn't have overcome such a reaction in such a short amount of time. (00:12:30 - 00:15:00)
Revealing mistake: In the scene with www.planetsolomon.com, you can see that it is a pre-filmed video (not a live stream as he said), as it has a time slider and play/pause controls etc. (00:13:05 - 00:13:45)
Continuity mistake: When everyone is in the living kitchen, Tommy ends up getting 2 darts stuck into the dartboard. When Harry throws the remote, the 2nd dart is missing. But it's back in the wide shots after Jennifer comes in. Later, when Tommy throws another dart, that 3rd one is seen, but not the 2nd one.
Factual error: Mary gives Dick directions to press Command-Q to close something. As Dick is using a Compaq computer which would be running Windows, he would not have a Command key and would instead have a Control key (which he actually is pressing) as the Command key exists only on Apple Macintosh computers. Ctrl+Q on a Windows machine doesn't do anything. (00:09:10)
Continuity mistake: Dick hands Nina a box full of dishes and asks for them to be cleaned. She then drops the box on the ground where it lands upright. All of the dishes remain in the box. The next time it's seen a few seconds later, it's suddenly on its side with dishes scattered across the floor. None of the characters touch it and there is no sound indicating that it magically tipped over by itself.
