Seeing some of the "blunders" in movies is amusing, but when people start scoffing at a movie b/c of said "mistakes" they just come off as clueless idiots (no, I'm not calling anyone here an idiot, I'm just venting in general). The more setups, the more locations, the more characters, and the more action all raise the bar exponentially for "errors" to happen. And Anyone who says, "ha ha, I wonder how that got past the director?" Has obviously never made a movie because the editor knows every frame of that film like the back of his hand. Nothing "slips past" post production. What probably happened was a conversation like this happend when the editor was screening a scene for the director.
Dir: I like it, but the water in so-and-so's glass goes from half-full to full when we cut back to her. Can we fix that?
Editor: Yeah, I noticed that too, but she really nailed that take. All the others she just seemed to be walking thru it. But that take was perfect.
Dir: Okay, keep it.
The point of a movie is to tell a story, not to achieve perfection in all things related to time and space. Unless you've been a part of making a movie you have no idea what a roving cluster f**k the shooting process actually is 🙂 And don't even get me started on post production...But it's fun, and that's what makes it all worthwhile. 😉
