Although Rhonda Fleming and Maureen O'Hara were both Titian-tressed beauties whom technicolor was seemingly invented, O'Hara was known for playing the kind of parts that she would have been playing in The Golden Hawk, that of a lady pirate. I wonder if Sam Katzman sent this script to the wrong redhead or he couldn't get O'Hara and settled for Rhonda Fleming.
As history I really couldn't quite figure out just when The Golden Hawk is taking place. We've got Spanish pirate John Sutton, French pirate Sterling Hayden, and English lady pirate Fleming. Add to that Helena Carter who is the promised bride of Sutton who Hayden holds for a ransom at one point. So we've got the nationalities straight, but I couldn't figure out the time and place historically for how these alliances seem to shift and change.
As for the casting these are all competent players, but Sterling Hayden is as French as Anna May Wong. As for Sutton, fine actor that he is why didn't Sam Katzman go get Gilbert Roland who would have been believable. Maybe he did and Roland turned him down.
The hidden plot gimmick is that there's something going on between Sutton and Hayden which I can't reveal. There are some nice battle sequences, but that's the best thing The Golden Hawk has to recommend it.
Maureen and Gilbert dodged a bullet with this one.
