RE: Heist 88 - Stealing Before Banks Computerize Systems

I haven't watched it, but from what you have narrates so far it seems, as if I have watched the movie
My question is that; if the movie filmed is based on a true life story, why is it that the money that was stolen in real life is different from the one in the movie. I guessed maybe they added some story lines to make it interesting.
Transition from one phase to another always brings a glitch in a system, that is why in recent Blockchain projects, they have to undergo a series of tests, before the mainnet.
For someone to plan and Steal that amount of money that year, that is to say it was well calculated and scripted.
From reading this, I feel as if I have watched the movie, thanks a lot.
