Corrected entry: About halfway through the film, Burt Lancaster's pirate crew gets captured & hoisted above the deck in a cargo net. Pause the DVD during that shot and check out the horizon on the left side of the picture. You'll see what appears to be a modern ocean cruising prominently in the background.

Directed by: Robert Siodmak
Starring: Burt Lancaster, Torin Thatcher, Eva Bartok, Nick Cravat
Other mistake: An antenna can be seen on the building above the grain warehouse.
Vallo: Gather round, lads and lasses, gather round.
Correction: The requirement to pause the DVD invalidates this mistake.
