Captain Scarface

 

Barton MacLane was a great character actor who probably played bad guys more often than good guys. He also probably holds the record for the person most often shot or beaten up by Humphrey Bogart.

In the 1953 film Captain Scarface, he plays the title character and he's definitely the bad guy. A tramp steamer named the S.S. Banos is torpedoed and sunk by a Soviet sub, with survivors machine gunned in the water to keep this act of destruction a secret. Well, everyone but the radioman Clegg (Paul Brinegar), who was paid off to make sure no SOS was sent. 

Captain Tredor (also known as Scarface) then brings a nearly exact duplicate into a South American port, with plans to continue on to the Panama Canal. There, an atomic bomb hidden on the ship will be detonated. It's a suicide mission, but Scarface and his crew are fanatics--willing to die to accomplish their mission.

In port, Scarface takes aboard a  Soviet scientist and his daughter, who think they are being helped to defect. Instead, Scarface is soon forcing the scientist to make sure the bomb will work. 

But there's a fly in Scarfaces's ointment. Sam Wilton (Leif Erickson) is an American who has gotten in trouble and needs to leave South America as quickly as possible. Circumstances land him on the ship, using the identity of another Soviet agent without at first realizing that's who he's impersonating. Fortunately, Scarface is expecting the agent, but has never met him.

Wilton doesn't know what's going on, but (despite his own shady past) soon realizes he'll have to do something to save innocent lives. Outsmarting Scarface won't be easy, though. The ship captain might be a fanatic, but he's smart as a whip.

It's a fun movie, generating suspense as it moves the story along briskly. A sort-of side plot involving two innocent middle-aged passengers plays out in a way that ends up intertwining with the main plot and adding a several moments of sincere heartbreak. 

The ending is a little anti-climactic, but overall this is a movie worth watching.
