Similar to google movies, apple is having a movie frenzy and including a bunch of recently released movies in 4k HDR. Doing this on my phone and can't find the actual link so just included a screenshot. Popular ones include:
-Terminator (Dark Fate) is 99 cents, $14.99 on google
-Knives out
-A beautiful day in the neighbourhood
-The gentleman
-1917
-The invisible man
-Dark Waters
Thanks OP. Some nice 4k stuff.
