Dogora (1964)

aka Giant Space Monster Dogora (1964)

Dir. Ishirō Honda

The mystery of disappearing television satellites in Earth's orbit, strange happenings at street level, and a detective hunting a well-organised group of diamond thieves would seem to be independent events to most onlookers, but in a daikaijū movie such things rarely are...

The alien creature, which resembles something from the ocean depths, isn't just attacking Japan, but they have a respected doctor who's researching something related, so they're better equipped to discover its weakness.

There's nothing particularly special or memorable about the film, so while it may be of interest to genre fans due to the creative talent involved (Ishirō Honda, Eiji Tsuburaya, and Akira Ifukube), it's one that casual fans can probably safely skip.
