iTunes is matching the recent Vudu/Fandango deal on the Indiana Jones 4 film collection at $24.99. The normal price is double this. All films are in HD, because there are no 4k versions at this time. If they do ever remaster these then iTunes may upgrade them like they have other films in the past, but there is no guarantee.
This is not a Movies Anywhere collection, so to will not transfer to any other linked accounts (e.g. Vudu).
For those concerned about the articles stating iTunes is going away, they are just changing the platform to split it into separate programs. Movies will go into a Movies app for Apple devices, but I believe Windows will retain the iTunes app. The point being is that your movies are not going away and are just moving to a new app in some cases.
