The main objective for Godzilla vs MechaGodzilla was to show that the special effects in Godzilla movies can be exciting and boisterous as the popular and more expensive effects from Hollywood films at the time.
When it was released in America in 1977 as part of a kiddie matinee, Cinema Shares was about to release the movie under the title Godzilla vs The Bionic Monster. Universal Television threatened to sue Cinema Shares for using the word "Bionic" in the title because they owned the rights to the The Bionic Woman series. So Cinema Shares immediately changed the title to Godzilla vs The Cosmic Monster.
After receiving visions of a monster attack, a shrine maiden must awaken King Caesar to aide Godzilla in fighting his robot counterpart built by aliens to invade Earth.
The movie is almost like a mishmash of several other movies we've seen. It's Godzilla meets James Bond with a hint of Planet Of The Apes. Why is someone from space always trying to invade Earth with a monster or robot? Haven't these aliens learned from the other aliens yet that no matter what monster you throw at Earth Godzilla is just going to come and kick their butts? Well, apparently not and they almost won too. MechaGodzilla does not screw around like Gigan, Megalon, and King Ghidorah do. Even though it was a 2 vs. 1 fight MechaGodzilla really over powered both Godzilla and King Caesar with all of its arsenal at its disposal.
Godzilla vs MechaGodzilla is another movie where the story is intriguing. It's more of a James Bond movie, but without James Bond and the villain are aliens instead of a mad scientist or terrorists. I guess at this time when the movie was made is when spy movies like James Bond are the most popular, so it is interesting how the movie incorporates those elements and still make it Godzilla related. Even some of the music sounds like it came from a James Bond flick.
Godzilla vs MechaGodzilla is not a bad movie at all. If you like movies like James Bond this is a movie you want to check out.
