One of the forgotten films of an Errol Flynn at the end of his career. I don't know if I can call myself an admirer of Errol Flynn's work, but it would be a mistake not to recognize his merit as one of the most remarkable and outstanding actors of his time. As the heartthrob of several adventure films, he continues to mark the collective memory as a pirate, adventurer and heartbreaker. It is still easy to find, on specialty TV channels, several of his films such as "Captain Blood", "Against All Flags", "Robin Hood" or "Don Juan"..., but this is not one of those iconic films that almost every we've already seen... quite the opposite. I'm certainly not the best person to assess the reasons why "Mara Maru" fell by the wayside and became an obscure film in the lives of everyone involved. What I do know, and I can say, is that Errol Flynn was already in clear degradation due to his problems with alcohol and that, during the film, I felt the actor was quite uncommitted to the role. Another problem is the story of the film, with a far-fetched script where, in the wake of a crime that is never quite clarified (although the film, between the lines, indicates the murderer), everyone sets off on a brief treasure hunt that turns out not to be the focus of action. What really makes the film work is the dramatic relationship between characters, in addition to the protagonist's struggle with himself, torn between good and evil. In fact, Flynn plays a frankly unsympathetic character in this film, we could even consider him an antihero, in part. He is a rude man, who is not necessarily mean, but he often acts in the worst possible way. A division that helps to understand why he became the lover of the friend's wife with whom he had a business partnership, and that explains the greed with which he craves treasure and his difficulty in giving up gain, after a certain point. The actor is good, but I've seen him in better shape in other works. Raymond Burr, Richard Webb and Paul Picerni make a very pleasant contribution, each in his own way. Ruth Roman stands out less... the actress is good and does what she can, but she was given very poor material and the character's character is unpleasant, indecisive to the point of seeming bipolar and quite one-dimensional. Gordon Douglas does a decent job of directing, although at times I feel that the film lacks the resolution of some loose ends. The film is not always happy with the construction and handling of suspense, and there is some predictability in the action scenes, but these are flaws that I felt were of little relevance. The cinematography is quite satisfying, and the scenes at sea or underwater are particularly well done. The sets and costumes are good, and the whole Manila environment looks good enough, albeit with perhaps few visible references to the eastern universe. The soundtrack, signed by Max Steiner, is quite good.
