- 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 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).
- 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.
- If rats and humans have the same life expectancies in Ratatouille as in Real Life, then the friendship between Linguini (human) and Remy (rat) cannot last for more than a few years.
- What will Linguini do after he no longer has Remy 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. Oh wait.
- Plus, it's not outside the realm of possibility that Remy 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.
- 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.
