Framed Stitch
Big Hero 6 might not be as popular as other animated films, but it definitely deserves the same kind of love. The characters are sweet and complex, and the story is great for all ages. Animators did not skip inserting even the most minute details into this film either.
Check out this screenshot. In the background you will see a bunch of framed photos. It would be very easy for animators to simply put random pictures or even just make the frames a little blurry- after all, who is actually going to look at them? The creators decided instead to sneak in an adorable little alien into the frame- quite literally. Hi, Stitch!
