Never seen that movie but did watch a documentary ages ago about fractional reserve banking yes.

The bank still uses the deposit money in that system. You are right to point out those same people on the street I mentioned would freak out even more if they knew that banks essentially lend out more than we deposited and also that they might sell your debt and all that jazz (I bet most people either never understood what happened in 2008 or forgot already other than a vague "yeah mortgage crisis")
