* A minor one is how suited Remy is to being a head chef. Not only does he have his highly developed sense of taste, but he also is rather good at directing and give orders. The brilliance behind this is the fact that his dad is the leader of their pack. Naturally, Remy would've inherited his dad's talent for leadership.
* Anton's food-induced {{Flashback}} hails from Marcel Proust's concept of "involuntary memory". Quoth ''[[http://en.wikipedia.org/wiki/In_Search_of_Lost_Time#Themes In Search of Lost Time]]'':
-->No sooner had the warm liquid mixed with the crumbs touched my palate than a shudder ran through me and I stopped, intent upon the extraordinary thing that was happening to me. An exquisite pleasure had invaded my senses, something isolated, detached, with no suggestion of its origin. And at once the vicissitudes of life had become indifferent to me, its disasters innocuous, its brevity illusory this new sensation having had on me the effect which love has of filling me with a precious essence; or rather this essence was not in me it was me. ... Whence did it come? What did it mean? How could I seize and apprehend it? ... And suddenly the memory revealed itself. The taste was that of the little piece of madeleine which on Sunday mornings at Combray (because on those mornings I did not go out before mass), when I went to say good morning to her in her bedroom, my aunt Léonie used to give me, dipping it first in her own cup of tea or tisane. The sight of the little madeleine had recalled nothing to my mind before I tasted it. And all from my cup of tea.
** It's actually a very well-known concept in France, used in common speak through the expression "''C'est ma madeleine de Proust''" (it's my madeleine of Proust).
* It's also brilliance that Remy distinctly chose a simple, but immaculately prepared, dish for Ego. Ego's the judge, jury, and executioner of restaurants all over Paris. He's probably been served the fanciest, most complex dishes the kitchens can cook up in an attempt to impress him. Ego is expecting this. Ego will not be impressed by any over the top attempt at culinary wizardly ''because'' he is expecting this. But give him the simplest, most wonderful "peasant food" in the world and that is going to subvert his expectation enough to pay attention.
* Colette's professional cooking instruction includes the decree, "You cannot be Mommy." But in the end, what wins over Anton is a meal that reminds him of what his mother used to make when he was a boy.
* The reference to Chef Boyardee is surprisingly significant, as he was also a well-known and successful chef that was reduced to a face on prepared foods after his death.
* The inconsequential fighting/kissing couple that Remy briefly sees in the beginning actually do mirror Linguini and Colette's first kiss (although Colette's reaching for pepper spray is more subtle). In fact, that first couple may have been where Rémy got the idea.
* Overlaps with FridgeHorror a bit, but remember how Gusteau make a big spiel in one of his interviews of how important it is for a creator to accept failure. So why does an unfavorable review end up literally killing him? Because creative people are their own harshest critics!
* Even though Skinner seems to get the last laugh at the end by [[spoiler:getting Gusteau's closed down for failing a health inspection]], he did get his comeuppance, in a way. From the public's point of view, Skinner knew that his restaurant had a rat infestation but covered it up, and [[spoiler:when he lost the restaurant to Linguini, he called the health inspector on Gusteau's just to spite him.]]

[[AC: FridgeHorror]]
* If rats and humans have the same life expectancies in ''Ratatouille'' as in Real Life, then the [[MayflyDecemberFriendship friendship]] between Linguini (human) and Rémy (rat) cannot last for more than a few years. What will [[LethalChef Linguini]] do after he no longer has Rémy to be the cooking genius?
** Oh, if only there was an accomplished, talented, and passionate chef with whom Linguini had a loving relationship that one can very easily imagine turning into marriage. [[OhWait Oh wait]].
** Plus, it's not outside the realm of possibility that Rémy could find a mate of his own and sire a few heirs, or at the very least take up an apprentice.
** Or Linguini could actually learn a thing or two from Remy.
* This is FridgeHorror only for oenophiles. The 1961 Chateau Latour that Skinner gives to Linguini is an exceptionally rare vintage. That one bottle would likely sell at auction for several thousand dollars. And he uses it to attempt to loosen the tongue of an unappreciative amateur.
* Pet rats and lab rats exist in this universe, where presumably all rats are sentient. Imagine what that must be like for them, either being experimented on or kept in a cage for no reason.
** This is actually addressed in one of the film's accompanying short films, which is called "Your Friend the Rat." In this short, Remy says that lab rats are "helping advance science." He also mentioned pet rats and didn't appear to send any negative connotations about it.
** Actual pet rats don't ''hate'' their cages, because their cages are their home and their territory. A rat that's allowed to free-roam will often rush back to its cage if it's startled or upset.
