Additional plot holes (spoilers!)
Spoilers!
In addition to the plot holes mentioned by the other poster:
In 1952, bills larger than $100 were all but non-existent. So "nearly $1,000,000" would have weighed nearly 220 lbs. (not the 115 lbs. including suit case indicated at the airports).
Also, it took 2 entire days (Friday night to Sunday night) to fly from LA to Rio on the way down (due to multiple connecting flights, and slower flying planes back then). Yet he was able to fly back from Rio in less than 12 hours??
And not only that, but on the way down, there seemed to be only one flight to Rio, yet his wife flew back first, then he flew back later and STILL managed to get to the bank by 8:15 a.m., lol.
I know this is a movie, but still...
