No, you have to have an Apple TV+ subscription.

Several of the links go to the wrong films, almost all of which are not free?

I guess it's a sign of getting old when I see the world classic and expect Gone With the Wind and Casablanca, but instead the list has Arrival, The Martian, and the Bourne Identity. The Sixth Sense is on the list for the US and it's a movie I coincidentally rewatched last night, again finding it to be a masterpiece.

In any case, very different list in Canada: Rocketman, Ford v Ferrari, Little Miss Sunshine, Catch Me If You Can, Jurassic Park, and the Proposal.

I loved this feature of Apple TV+ when it was more consistently offered a few years ago. Having a curated list of rotating popular old movies made it easy to pick what to watch.
