Off topic: the police cars in the movie RoboCop were Ford Tauruses. I thought it was pretty cool how smoke came off the front tires when they peeled out.
The murder victim was found in a room that was locked from the inside! In real life it’s easy to lock a door and close it behind you as you leave, but apparently the mechanics of locks are vastly different on TV.
I maintain such a look easily, and cannot get rid of it. Light skin and dark hair makes it look like you have perma stubble 5 minutes after shaving.
Joe Hamm is one TV example. He was shaved 3/4 times a day when shooting Mad Men and even then looks like he has a shadow half the time.
The mechanics of locks did used to be very different, so when Philo Vance was confronted with a locked room body with the key inside the room in the lock in the 1920s, it was a legitimate puzzle. When Mrs. Fletcher was confronted with the same thing in 1980s, it was a case of not doing the research.
Wait, you can join the army to become a safecracker? Cool.
Being able to turn on the radio or TV to the exact news story you want.
Being able to hack into any computer system you want to and change the information. How does Hardisson of Leverage do that? I guess the same way Spencer knocks people out with a single punch.
While we’re at that, knocking out people with a single hit to the head and causing no major medical complication.
On TV, sure. Why not?
Not only that, after they knock the guy out, they take their sweet time doing whatever it is they need to do, as if the guy they knocked out is taking a 4 hour nap. When people get knocked out like that in real life, it usually doesn’t last for more than a few seconds.
Also, car keys in the sun visor. Who the hell does that?
Not like it’s an invisible post. 
There are certain locks that you can only lock from the inside like chains and some types of bars.
As far as huge billowing clouds of tire smoke, I saw quite a bit of that in my high school parking lot (back when muscle cars were still fairly abundant). There were several yellow speed bumps heavily decorated with rubber.
This just happened last night on Hawaii 5 0–
Two totally unrelated deaths.
McGarrett: These two murders are related, I can feel it. Check the calibers!
Other Guy: Hey, they’re both the same caliber. They must be related!
Me (totally regaining my disbelief): Bwha?
Well, depending on your definition of “related,” that pretty much cinches it.
Cell phones that produce a dial tone when the person on the other end disconnects. Actually, that’s one that I’d like to see. How hard would it be to make the phone produce a simple tone upon disconnection so you don’t keep talking to someone who isn’t there like an idiot?
In real life, someone who’s knocked out for more than a few minutes is unlikely to ever wake up again without medical intervention.
Of course, in movies & TV, a knock to the head is a convenient on/off switch. Knock 'em out, and they’ll remain unconscious for as long as needed, and they just need smelling salts or a hose to the face to wake 'em up again. (The Chevy Chase movie Funny Farm did a hilarious inversion of this trope – in the scene where a fisherman gets a hook stuck in his neck, Chevy tries to knock him out TV-style but only manages to beat the living piss out of him.)
Jitterbug phones have a dial tone.
Well, they make a special electric razor for this, so sure you can- assuming you have electricity. But not when you are lost in the desert or a castaway on a island…
Without a bullet you cant tell a .38 from a 9mm, just based on the hole. So, pretty much there are about half of all handguns commonly used.
And a .45 hole is just like a .44 hole.
Which blew my mind on Hell On Wheels when some Pinkerton (?)was tracking down the protagonist based on his rather rare handgun- which of course was a black powder cap & ball, with the exact same ball as half the other black powder cap & balls revolvers in America.:rolleyes:
Even with a recovered ball they wouldnt be able to tell which brand of black powder cap & ball revolvers it came from.
OK, make me feel old.
I just want it to make some sound to indicate that the call has been dropped. I have to keep talking until I expect a response and fail to get one, then call back and find out the last thing the person I was talking to heard.
