Other mistake: When Withers is training Harry,Bernie and Alfie to be firemen at their hideout,the second scene of them descending the ladder with a man over is shoulders is reused from earlier in the film when the gang were at the fire station watching the real fire men training ,the giveaway being the modern fire engine parked next to the ladder .
Other mistake: When the crooks are in the bank vault ,they hear another fire engine coming ,the fire engine seen driving through the streets isn't the same one that arrives at the fire.
Other mistake: When the villan's car is stopped by the traffic jam, the background projection is still moving.
