Blows to the head knocking someone out for exactly as long as is convenient for the plot with no long term consequences whatsoever. Even otherwise “realistic” shows and movies are guilty of this. In reality, and blow to the head strong enough to knock you out is likely to cause brain damage or even death.
Also in westerns shooting someones hand to drop their gun, a shot from a .45 long Colt round would completely destroy their hand.
#9 is real though; just use the command "login --security-override /nopassword" with whatever username you need to get the files and you're in. Works on all systems; it's a hardcoded back door.
The huge progress bar indicating how much of the mainframe you've downloaded to the puny memory stick though, that's fake as hell!
#8 That's why I love the scene in "Goldfinger" were Mr. Bond is about to get cut in half with the laser.
Goldfinger: ... .good night Mr. Bond * and walks away*
Bond: Do you expect me to talk?
Goldfinger: No(!) Mr. Bond, I expect you to die!
Actually, firearms with silencers can be very quiet, depends on cartridge and whole system though.
Fast and furious movies tick me off the most. They never stop for gas and after causing multiple car crashes with multiple fatalities (and their car flips countless times while crashing) they are always able to walk away without broken limbs, laceration, cuts or bruises.
only in the movies though, apparently..
