Revealing mistake: During the courtroom scene, one of the ghosts grabs the prosecutor and she is hanging upside down. Her dress comes down a little, but when she is about to fly through the door you can see part of the dress is pinned to her panty hose to stop the dress from falling off. (00:33:30)
Suggested correction: She's not wearing pantyhose, she's wearing stockings with a garter belt, that's the part that is 'pinned' to the hosiery. The skirt does seem to ride up (I mean, upside down) a bit but it could have latched onto one of the clips.
Visible crew/equipment: When the chairs are flying through the air in the courtroom, if you look closely, you can see the string pulling one of them. (00:34:30)
Suggested correction: This would need more clarification. I couldn't see any string in the mentioned sequences - and for the record, I don't think strings were used, you can easily find interviews with the production team that mention the different trick at work here (they quite literally 'shot' the chairs up in the air).
Continuity mistake: When the Judge states his sentence, from Stantz's POV of the front of the table the pink goo in the jar starts bubbling with a tag hanging on its right side. From a wider angle of the front of the table not only is the tag not visible, but the ghost trap next to it is different (check the number of dials and looks of the box), plus the trap is now slightly skewed as to how it was positioned before. (00:31:45)
Suggested correction: I believe the tag is visible at all times, at least the string of it (the tag itself in the wider angle from the defence's table is hidden by the jar itself). Not sure about the mentioned box, you mean the ghost trap? My impression is that the different angle accounts for a perceived different placement, but it's just my perception.
I've seen it again and can confirm that the tag is missing and even the wole set changes. Picture is online.
Revealing mistake: When the [superimposed] pink slime and the bending tub try to attack Dana and Oscar, watch the tiles on the wall in front and you'll notice that they're not being reflected, just an empty space.
Suggested correction: The area circled is the reflecting surface. Which means the reflection (if it was even visible in the tiles) would appear as far to the right of the wall as the slime is to the left. It would be off-screen.
Just watch the movie scene for Christ's sake instead of basing your junk correction on a picture.
What is in the movie that would change the basic principles of optics? The picture is pretty clear as to what the setup is.
The camera moves around the bathroom and thus proves that the pink slime isn't reflected anywhere.
If that's the case, why did you illustrate the error with a frame where the reflection would not be visible? Can you post a picture where the reflection of the bathtub is visible but not the slime?
The wide shot has Sigourney Weaver running and thus a blurry image quality. Nevertheless, I'll try to get a good image. In any case, no-one expects someone correcting a mistake without checking the actual mistake.
Having checked the actual scene, the tiles do not reflect Sigourney Weaver either (who is reflected by the mirror, instead), and what appears in the tiles highlighted by the screenshot should be the reflection of the sink and toiletries directly in front of the reflecting surface. I am not sure that from that angle it'd reflect anything happening in the room that can be caught on camera.
Continuity mistake: At the end of the movie, the Statue of Liberty is looking down into the window of the art building. When the Ghostbusters come out of the building, it's on the ground.
Suggested correction: That is intentional since the power of the slime had been neutralizer. The statue was just a statue again, so fell over.
Continuity mistake: When the movie ends and all of the heroes exit the museum while the people cheer; they walk down all the steps, yet from the opposite angle they're back on the top and walking down again. (01:39:50)
Suggested correction: It seems to me that, with two sets of railings, the camera cuts away when they reach the end of the first railing, then when they get to the end of the second railing it cuts away again, for an extended time to show the crowd, and then when it cuts back to them they are at the end. It's not a flawless transition, as you rightfully point out with the 'Ray and Egon hug' mistake in the same sequence.
