Interpol - 1957 - 6/10
AKA - Pickup Alley

The underrated Victor Mature stars as a federal agent chasing a narcotics ring.
Small fry are easy enough to catch, and for the criminal organization, easy to replace.
The top man has never been seen. His name, perhaps an alias, is McNally.

Trevor Howard is memorable as the smooth, calculating mastermind, seen above with Anita Ekberg who acts as courier, bait, decoy, whatever is necessary.
Filmed between London and the US, but also includes jaunts to Lisbon, Naples, Rome, this recalls To The Ends Of The Earth (1948), but that was more procedural and this more character driven.
Watchable throughout, though I did find myself starting to root for the narcotics ring.
