Iinternet Movie DataBase (IMDb) had lists of gaffs for most films
I find some really annoying. Almost like they are treating the potential audience as not intelligent enough to notice when something glaringly wrong is done. I like aviation films, as an example, and they are often so full of holes. They really rattle me sometimes! lol
B727 (3 jet engines, rear mounted) takes off, a B747 in flight (4 wing mounted jet engines) and B767 landing (two wing mounted jets). B747-400 shown from the outside and crew of three (including a flight engineer) in the cockpit. B747-400's have a two crew cockpit (as do most modern generation aircraft). The amount of twin jet engined helicopters that have single piston engined Bell 47 sound when flying or on the ground is quite remarkable. And the real major annoyance are the jets that are diving toward the ground complete with the sound of a single piston engined fighter type diving. Cockpits are always massive and have loads of space. In fact most cockpits are quite cramped because there is no money to be made from the space being used for the poor pilots. Very few aviation films have kept my respect for good efforts. For me it is poor attentiuon to detail and an insult to the audience. They spend millions on films, I doubt it would be any more expensive to dub authentic sounds rather the sound archive ones that get used. Obviously I am touchy on this as it an area of interest I have. I am sure many notice it on many other topics.
The Airplane parodies are not short of material from the true aviation films to be able to mock. I think there is less excuse for such glaring errors these days than there were in the past. The technology now is so good they can make things accurate.
I'll shush now ;-)
