My observances:
1) There is no such thing as "bed-hair" in Hollywood movies. Everyone wakes up with a perfect hairdo, no drool, no groggy eyes, no stumbling/being off-balance. Bright-eyed and bushy-tailed, the whole lot of 'em, no matter what time of night they are awoken! Amazing!
2) When being chased, the chasee must always turn several times to see how close the chaser is to them, as opposed to just running in a straight line as fast as he/she can.
3) When being chased at home, the chasee will always run UPstairs, instead of out the first floor door/window.
4) You can blow up a car by shooting a single bullet through it's gas tank. (De-bunked on Mythbusters).
5) The Hero can drive any sort of vehicle known to man with no lessons needed; be it a tank, plane, motorcycle, jeep, or helicopter.
6) All vehicles will have ample amounts of gas in the tank, until the vehicle turns down a dark country road.
7) Hesitating car engines can be started easier by whacking the dashboard and shouting, "Come on, you! START!"
8) Same theory applies to phones when calling someone. Saying "Come on, come on, PICK UP THE PHONE!", when it's ringing, as if the person can hear you.
This is FUN!
Well, you sure *done good* with your observances! Those are all great, and every night at the movies or on TV, we're going to see at least one or two of them!
Don't stop now - bet you could find some pics for some. :)
Also, when being chased down a road by a car, our hero/heroin, on foot, always runs in a straight line. Leaving the road would violate the rules.
