I freaked out when I noticed this! You see how on each side of the chapel that Maria and Manolo are standing are murals of the sun and moon? That CANT be a coincidence!❤️💛☀️🦅🦇🌙💚🖤
Yes the Book of Life is an absolutely amazing movie just as it is. I just think it would be a funny concept to imagine if Manolo had been the one to go away instead of Maria. Instead of coming back to find that Maria and Joaquin got together, it goes exactly the same as in the movie, but now Maria and Joaquin are fighting for Manolo's attention.
Just imagine he gets sent away and comes back all grown and with his swoosh hair and epic music skills... I just think it would be funny
