As a 4K Blu-ray nerd, these are the boxsets I'd buy this Prime Day

Few directors merit 4K discs quite like Christopher Nolan, whose films have always been visual spectacles with soundtracks that really benefit from the best bitrate possible. This box set compiles all his big movies with Warner Bros (before the move to Universal), so you're unlikely to ever see a more comprehensive one. Including all his Batman movies and some other modern classics like Interstellar and Inception, 15% off this sort of huge collection is a great deal.

This was my first ever 4K Blu-ray purchase, and it's a brilliant one if you love Peter Jackson's Tolkien films. This stunning remaster brings the movies into staggering new quality, reversing some distracting colour-grading choices to give you colour and clarity that got me quite emotional the first time I rewatched it. Again, 15% off is well worth grabbing for some of the most beautiful films ever made.

Sacriligeously, I'm actually not that big a John Wick guy, but there's no doubt that the series has many fans – four entries underline that. It's also a collection that has some superb sequences for TV testing, especially where nightclubs and other dark sequences play host to shootouts, giving contrast and black levels a real test. Again, 15% seems to be the standard, and it's well worth grabbing.

This is the most modest saving of the lot, but it's on a trilogy of movies so beloved that they need to be included – Edgar Wright's Cornetto Trilogy. What a run of films, establishing him as a fan-favourite director and redefining what comedy could look like in editing terms. This is quite simply the best way to watch all three, and getting each for the price of a standard Blu-ray makes this box set a top pick.
