Korean rip-off of "King Kong".
Giant ape escapes ship and invades Korea. During his rampage he grabs a beautiful girl, played by Joanna Kerns (in her first role, who later be on TV's "Growing Pains").
Originally, the Koreans wanted Rick Baker to do the ape costume, but he was busy working in "King Kong", so they ended up buying a gorilla suit from Don Post Studios.
Also, this is one of the earliest films where a giant monster give the camera the finger.
American Trailer with French and German subtitles.
