I have seen this in countless movies and tv series and it just irritates me... Character gets to know the numbers of a code (ussualy the numbers are more worn out that the unused ones, here he did it by putting the thin film over it) and than just guess the right sequence. In most cases, the script just glosses over it, here they used the "it's just a numbers game" explanation, but it's still a BS. There is no way he could have guessed it without additional info.
He did have a little bit of time punching that code, and with only four specific numbers to chose from it's not that many sequences to go through. Let's say the numbers are 1234:
1234 1243 1324 1342 1423 1432
2134 2143 2314 2341 2413 2431
3124 3142 3214 3241 3412 3421
4123 4132 4213 4231 4312 4321
That's it, that's all the possible combinations (without repeating the same number - which four digits on a four number code is clear evidence of not happening.
So all Ray has to do is punch a MAXIMUM of 24 different combinations of the same four digits, to crack the code. Not impossible by any stretch of the imagination, and I have done the same thing once back in the mid 90's when I forgot the entrycode to my workplace. Four keys on the keypad were worn down, so I took a wild guess that those were the numbers and just started punching away. It took less than ten combinations before I got the door open.
True, but that's only the case when you have infinite tries and it doesn't lock down after two or three tries. They don't specify this in the movie, so lets assume it doesn't... Legit point, thanks.
However, my point still stands with other movies or tv series... I have seen countless times when the hero just figures the numbers and then punches the combination and it works the first time.
Agreed! Figuring out the correct 4-digit combination from just knowing which four digits it contains is if not impossible then at least highly unlikely. You have a one chance in 24 to get it right on the first try. :)
