I saw someone do a demonstration once, they took a box of "iron-fortified" breakfast cereal, dumped it into a bowl, then ran a magnet through it. The magnet picked up some of the dust from the bottom of the bowl, that dust being the tiny iron particles that were added to the cereal to "fortify" it.

4k77, 4k80, and 4k83 are 4k (hence the name) versions of Star Wars, The Empire Strikes Back, and Return of the Jedi, respectively. 4k77 was mastered from an original 1977 35mm print of the movie. I'm not sure of the other's sources, but they're probably similar.
There's also the 4k77, 4k80, and 4k83 projects which made 4k versions of Star Wars, The Empire Strikes Back, and Return of the Jedi respectively, all from original 35mm reels of the movies.
I put them in quotes as the word has no objective meaning as applied to a breakfast cereal, it's simply a marketing term. I did not intend to imply that ingested iron particles are not a valid source of iron for human biology.
