Notre Dame de Paris. Romeo and Juliet is a modern French-style adaptation based on the original work. I like it very much, but since you have already read it, I won’t recommend it again.
I have already watched Le Petit Prince and Mozart - L'opera Rock, both of which are classics!
The adaptation of "The Little Prince" is more essential, after all, it is the original country. Because it is based on children's literature, the overall style is relatively light and dreamy, and the singing style is also different. Some of the treatments really give me goosebumps~
"Rock Mozart" is relatively "adult", There are many sexy and hot scenes, and some of the lyrics are unabashedly Gothic and borderline sentimental, which is very different from the "prenatal care professionals" we have in mind! The French musical "Mozart on Rock" is nicknamed "Fazza" by theater fans. It is often compared to the German musical Mozart, nicknamed "Dezza". The plot and interpretation angle are different, but they can all be justified, just like the differences between diamonds. The cross-sections complement each other, and it is recommended to appreciate them in association.
By the way, "The Phantom of the Opera" is an English musical adapted from the original French work. If you are interested in French culture, this one is also very suitable for viewing.
