Acclaimed Flop: While it did not lose money, Princess and the Frog did not quite meet Disney's expectations. The revival of traditional animation was fully banking of PatF's performance, and despite fantastic reviews, it only did okay.
The weird psychedelic filter effect on Dr. Facilier's face as he sings "I hope you're satisfied" during his Villain Song seems to hearken back to one of the posters◊ for They Live, a horror movie in which Keith David, Dr. Faciler's voice actor, starred prominently. Actor and character also both share a gap in their front teeth. May or may not be intentional, but when you think about it, doesn't Dr. Facilier end up as a kind of a gargoyle at the end?
Anika Noni Rose is left-handed as well, and specifically requested the animators to make Tiana left-handed.
Celebrity Voice Actor: Surprisingly averted for a Disney film with the cast mostly being made up of character actors and actual voice actors. A few cameos aside, the biggest names in the cast are John Goodman and Oprah Winfrey. Emeril Lagasse is in there too, as a crocodile who yells "Bam!" a lot.
Dueling Movies: Disney released The Princess and the Frog against 20th Century Fox's Alvin and the Chipmunks: The Squeakquel and Avatar. Disney fans as well as non-Disney animation buffs question on how Disney made a big mistake.
Genre-Killer: Not in the literal sense, but Disney banked their interest in returning to do Traditional Animation films by how well Princess and the Frog performed at the box office. It did ok.Tangled came out the next year and gave Disney their highest numbers since The Lion King. Disney would once more say they had no plans to do traditionally animated films in the foreseeable future.
Throw It In: Originally, the plan was for Naveen to say "That's new" after his vocal sac inflates suddenly in a surprised tone of voice (i.e. "Whoa, that's new.") However, Bruno Campos said the line in a suave tone of voice, making the scene arguably much funnier (especially since his new tone of voice makes it sound more like "That's a new feature", in other words, that he's trying to pretend he already knew about it).
In an earlier script, Dr. Facilier wasn't just a dark wizard who wants to conquer New Orleans with the help of his Friends on the Other Side - he would have been Mama Odie's son, who followed the path of the dark arts unlike his mother. In this same script, there was to be a showdown between the two of them, which would have converged into a major battle during the Mardi Gras. Also, Facilier was originally named Dr. Duvalier after Francois "Papa Doc" Duvalier, the Voodoo practicing genocidal dictator of Haiti.
Early concept art◊ depicted Charlotte with long hair and a large gut that she kept hidden with a corset.
Word of God: Facilier's look was modeled on the voodoo god Baron Samedi: he's lean, he wears a top hat and cutaway coat, his logo is a skull with a top hat, and at one point he sports a skull mask. Bruce Smith even describes Facilier as the love child of the Disney Villains Captain Hook and Cruella De Vil.
