MARA MARU (1952)

Routine adventure drama with Errol Flynn.  I was hoping it was going to be a jungle movie with that title.  Turns out he's a deep sea diver and salvager.  His partner (Richard Webb) is killed and he can't figure out who was behind it.  His partner's wife (Ruth Roman) is always hanging around.  Raymond Burr plays the bad guy.  When Flynn won't go down to some shipwreck for him, Burr causes his boat to explode by putting a shiny thing on it so a kid will pick it up.  Yeah it's just as interesting as it sounds.  Flynn finally does what Burr wants, brings up the loot in the middle of a storm, but he breaks the compass so Burr will need him to get back to land.  I've only seen one other Errol Flynn movie, his last one, Cuban Rebel Girls (1959).  It's a little better than this one.
