Bought a TV recently.

I can't work out which of the numerous movies in the Google Play app are available to choose from for the free movie offer.

There is no 'included' section.

I picked a few new movies at random and all were asking to pay £13.99 for UHD. Eventually when I clicked on Spider Man Homecoming, I saw an option to redeem an offer.

Therefore I conclude Spiderman is one oif the options.

How on Earth do I figure out the rest of the choices?
I actually wanted Bladerunner 2049, but I do not believe this can be selected for free.

Anyone able to help please?
