Eight Billion $$$ ?!?!
Gin arranged everything including the accounts to transfer the eight billion $$$.
How the hell did Mac: 1) get access to the accounts, then 2) manage to convince the authorities there was only seven bill $, then 3) access and arrange one billion for Gin?!?!
CORNY ENDING!!! What a waste to a pretty good movie... including a 60 year old taking a split second to jump over train tracks... he ain't Bond no more!
