Goofs

Near the end, when the '56 Studebaker police car turns into the alley adjacent to where the criminals are melting down the gold, it is seen from another angle, and it's a '57 Ford.

Early in the movie, how a guy jumps off of a bridge . . . in the pouring rain . . . on to the top of a high-speed train without an incident is a bit unbelievable. Then, they throw a switch/turnout to put the train on to the wrong track and get it slowed down to a complete stop (still in the pouring rain) is never explained.

The trucks are fitted with California registration plates all along the 500 miles they travel. California plates with arouse immediate suspicion with the police in roadblocks in all the states they had to pass.

When the Cadillac is heading on the freeway to the final destination, the six passports of all involved, are pulled out, but the three characters in the car know that the other three are either dead or caught. Why would they be carrying those extra three unnecessary passports at this point? Since they have just stated that the clothing worn before - including the work gear from the foundry have been burned, it would be assumed that those unneeded passports be burned also as they would be useless at this point, and connect them to the others. They state that they will ditch the passports later upon destination. Coming to a traffic jam, they are stuck with the passports, but no mention is made of this if police do a search of cars and trucks: the two men captured at the weigh-in stop could have snitched on the others identities, and they would not be able to toss the passports in heavy daylight traffic.

A crew member rushes to the side of the road (and hides behind a bush) right after the tanker drives off the roadblock where one of the gang members has been shot by the police.

When they take the gold-fitted car out of the garage, the crew can be seen in detail in its reflection.
