Someone else here just mentionned the similarities in design between The King and Queen of Everything and the Celestial Dragons.
I looked up a little about the movie; and it seems that is quite a common knowledge that it might have a lot of connection between the movie and One Piece.
Namely :
※ Gol. D. Roger being Baron Munchausen
※ Van Augur taking inspiration from a character of the movie
※ Ray D. Tutto being possibly the D. stuff
※ And Kizaru flying on Cannonball being similar to Baron Munchausen doing kind of the same
