An All-Princess Movie

I don't really think that's a good idea. All of the Princesses are from different places and time periods, so it wouldn't make sense for a movie. Like, by the time Tiana becomes a princess in the 1920's, Pocahontas, Mulan, and Aurora would be long gone.

I prefer to save that sort of stuff for fanfics where them meeting up can be easily explained by wormholes, magic, alternate universes, ect.

BTW, isn't this more of a forum topic? Since it's a creative thing with no real answer?

This sounds like what’s going to happen in Enchanted 2 LOL. I think it would be a bit OTT because they are from different time periods and if they were going to make it into a live action movie then the director would have to hire actresses that are similar to the princesses. Example would be Amy Adams could be Ariel as she was the dead ringer of her in Enchanted , Resse Witherspoon could be Cinderella and Anne Hathaway could play Belle. Maybe Hollywood might do that some time as Enchanted was a success back in 2007. Sorry for bringing Enchanted into this but it would turn out to be a déjà vu of that film.

I guess so and I'm not sure yet.

Amy Adams was the best princess in Enchanted as Giselle . She is the my hero in the movie and she was great in it. But that is not your choice is my choice who is the best one in Disney.
