Not that I like to defend Hollyweird, and they do make plenty of mistakes: how many times have you gritted your teeth and tried to suspend disbelief when the car chase has tires squealing on unpaved roads? The explanation I've always been given by those in the industry for such things is that doing so is a "convention" that the movie goer expects. Well, either they know their market, or they underestimate the intelligence of the average movie goer.
However, often such things as cocking the hammer back on 1911 are simply trimmed in the cutting room. Sometimes it is integral to a scene and is left in for dramatic effect, but when they are trying to trim a two hour and ten minute movie down to under two hours they cut seconds where ever they can. Doesn't necessarily make for a good movie, but most of goobs who go to these things haven't got the attention span to spend any more time sitting still than about eighty to ninety minutes.
That beings said, Hollywierd doesn't care about reality, they simply want to put out a movie that will get your dollars into their pockets.
Yeah, I'm one of the ones who has enough vestibular sense that I had to leave that obnoxious one with the shaky camera. From what I saw of it it wasn't worth the bucks for the ticket. Glad I didn't pay for that one!
I normally avoid theaters because I don't like watching a movie while some moron sits and chats on his/her cell phone. Worse are the people in the next isle who have already seen the movie twice and insist on tell their friend next to them what will is about happen. It only gets worse when the movie is full of bad mistakes concerning firearms, or cars, or both.
I've got good friends who drag me to a movie once in a while, but I prefer to watch movies on home theater when the DVD comes out. Costs less money, I can make the popcorn with real butter, and if I need to go to the restroom I can stop the machine and not miss anything.
