Destroy all Monsters
Godzilla, Rodan, Ghidorah, and several other of Toho's largest monster stars all appear in this alien invasion movie.
It's got giant rubber monsters, an alien invasion plot, horrible dubbing, aliens in sparkly clothes, the works.
It's been my childhood go to Godzilla film for monster brawls, and here's hoping it can get a good natured ribbing.
Here's a trailer for it and everything.
