I heard that one of the Godzilla storylines they’re considering for a sequel is Monster Island from Destroy All Monsters. That movie was about Japanese government relocating the monsters onto an island to have them contained. If you can’t destroy something, at least contain them. In the movie, a race of aliens come to Earth, take over the island, and install remote control devices inside the monsters and staff of the island and use the monsters to try and destroy the world.
Course, the idea of aliens is probably not the right way. I picture the organization Monarch led by Dr. Ichiro Serizawa (my favorite character in the movie) had discovered other prehistoric monsters like Godzilla prior to the movie and had been secretly keeping them contained on an island. I’d like to see Rodan, Mothra, King Ghidorah, Anguirus, or Destroyah. My top favorite monsters. But the monsters escape the island and so our heroes have to once again bring in Godzilla to stop them. Also, I thought it would be cool that after this movie, that Godzilla could be more of a bad guy for a little bit. In the new movie, he was like a protector of nature, maybe Godzilla could see man has a destroyer of nature and tries to restore the balance. That way Godzilla could a villain for a long bit of the movie, then once the monsters escape the island, he turns his attention to them.
I think it would be cool. I’m sure they got better ideas up their sleeves.
Course, I’d like to see MechaGodzilla, but I don’t think it would be possible to built a robot replica of a 400 tall monster in this world. The money it would take to build one of those would take more then the national debt, unless they use aliens, if they go that route, which I don’t think they would.
