John Wayne is veteran skipper "Capt. Ralls" who discovers that his employer has pinched his girlfriend - "Angelique" (Gail Russell) so with revenge in mind, he runs his ship - laden with $5m in gold bullion - aground at a secret location and is soon on the run from his erstwhile boss who knows the scuttling was deliberate and who wants his loot back! What ensues now are series of entertaining escapades as Duke wrestles all sorts of giant sea monsters; tries out pearl fishing; saves his best pal and tries to get his gal back - all as well as salvaging his plunder and staying one step ahead of the scheming "Sidneye" (Luther Adler). It's a well constructed, fairly action-packed film this - and it gives the star much more chance to demonstrate a little more depth to his character, with a script and pace that gives the story quite a compelling nature. Adler is great as the sleazy magnate, and the direction creatively uses the sweaty and moist environment to good effect - you almost expect Orson Welles to appear somewhere. It doesn't always work - there are some flatter moments especially in the third quarter of the film, but it all picks up well and Russell is on really good form engendering some charming and lively chemistry with both of her gentleman friends. I was a little underwhelmed by the conclusion, but all told this is certainly at the top end of any of their work - and it is well worth a watch.
