Where do the movies take place, chronologically?
It isn’t really possible to fit the movies into the series continuity. In the R movie, Chibi-Usa (Rini) appears. She leaves at the end of the R series, which means that the R movie could only happen if the Black Moon villains are alive but for some reason not doing anything during the movie. In the S movie, Uranus, Neptune, and Pluto appear. Pluto is gone before the end of the S series, which means that the S series villains would also have to be alive but not doing anything. Furthermore, Hotaru does _not_ appear in the movie, yet in the series she appears before Pluto reappears. (This movie was based on a manga story, and probably fits into manga continuity.) In the SS movie, Pluto appears, yet in the Sailor Stars series, the Senshi are surprised to learn that she is alive. Also, Uranus and Neptune get versions of their new attacks in this movie before they actually do for real in Sailor Stars.
