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)
Continuity mistake: In the scene where Dick is buying a laptop, you can see that while the computer is on his lap, it is not really on. (00:06:40)
Continuity mistake: The bottle of orange soda on the breakfast tray Dick tries to bring to Mary changes to a bottle of alcohol (Jack Daniel's I believe) when he sets it down. It later changes back into the bottle of orange soda.
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)
Suggested correction: During streaming, any video player can be used. Meaning "play" or "scroll" buttons are still visible, just not functional.
The color of non-functional buttons will be muted. You can see in the picture that the stop button is solid black, indicating that it is functional. The marker on the status bar is also partially advanced. In a live stream, the marker would remain at the beginning position unless someone paused the stream, in which case resuming play would cause the marker to advance in order to catch up to the delay. In this scene, Dr. Solomon is teaching his class and interacting with his students, meaning no-one paused the stream.
Dick's Big Giant Headache (1) - S4-E23
Continuity mistake: After Harry eats the egg, the lid is still up. When Vicki walks in, the lid is down.
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.
Continuity mistake: Mary's glass of wine goes from being almost empty to about half full during her conversation with Charlotte. In the same scene Charlotte goes to put the bottle down but in the next shot she is still holding it.
Continuity mistake: During a conversation between Sally, Mary and Nina about posing for "Playpen" magazine, Mary's glasses are on one second, and then off the next. This mistake repeats twice in thirty seconds. They're nowhere to be seen otherwise. (00:13:30)
Dick's Big Giant Headache (2) - S4-E24
Revealing mistake: When Stone is about to drop the bowl of punch on Alissa from behind her, you can see she braces herself for it before he starts pouring it on her (she knows it's about to come when he says "Oops"). (00:13:05)
Continuity mistake: In the scene where the F.B.I. storm Dick's house, Charlotte's sleeves change length (i.e. being pulled up or like normal) throughout the entire scene. (00:20:00 - 00:20:30)
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)
Other mistake: In the scene where Don arrives at Dick's 'party', he looks at his non-existent watch. (00:13:25)
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.
