Gosh, no! That's not at all their concern. It's entertainment, pure and simple. Which means it has to sound cool. That's it: Look cool & sound cool. Accuracy is not an issue. Don't believe anything you see or hear in a movie. For that matter, don't automatically believe what you read, either. Check out MovieMistakes.com and/or SlipUps.com for lots of examples.

My favorite, from Die Hard II:
"That punk pulled a Glock 7 on me! You know what that is? It's a porcelain gun made in Germany. It doesn't show up on your airport X-ray machines, and it cost more than you make here in a month."

There has never been a Glock 7. They started at 17 & currently go up to 36.
Glocks are made of polymer (plastic) and lots of steel...
so they show up just fine in xrays and on metal detectors.
They are made in Austria, not Germany...
and are really quite affordable as guns go.

Don't believe what you see in print, either. Fiction is fiction and news is ... usually slanted by the editor's bias. Often, the editor has not even declared a bias, so it's up to you to work it out.

Stay safe,
