As a 4K Blu-ray superfan, these are 7 discs I'd buy in the Prime Day sale

Often quoted as being the ultimate disc to test the best-of-best audio-visual systems. If you've got one of the best OLED TVs in your possession, plus a superb surround sound system, then this will push it to the limits.

I remember watching this one afternoon in a Dolby Vision-certified cinema in New York City. It's lived with me ever since for its sheer visual impact – and this 4K format is the next best way to ever see it.

The Martian is a truly exceptional movie – as its audience and critics' scores reflect on Rotten Tomatoes, at 91% apiece.

That score should be even higher for this 4K Blu-ray version, however, as the high dynamic range (HDR) re-grading gives so much extra zing the the colours and brightness – it changes how this flick feels.

Okay, I know, this isn't one for everyone – I'd thought the same until I experienced a classic scene in a custom-built cinema room the other month.

That experience showed me that The Greatest Showman is worth it for the soundtrack alone – and, in particular, the way it's so perfectly visually matched and directed (even to actors who aren't actually singing).

It's much-loved by audiences, too, with 86% on Rotten Tomatoes proving that point – to the contrary of critics.

Perhaps one of the best films ever made (a view I stand by), with 6 Oscars under its belt to help prove it – plus a 95% rating on Rotten Tomatoes – the 4K Blu-ray of Forrest Gump only adds to the viewing experience.

The 25th anniversary re-release saw an all-new Dolby Atmos sound mix, really adding to those Vietnam scenes, whilst an HDR re-master also ensures added pop to the visuals.

Arguably a contentious addition, in part as the camera formats used to shoot Sinners deliver the majority of the movie in a 2.76:1 aspect – meaning huge black bars top and bottom. Make sure you watch on an extra-large TV, therefore!

If you do, however, then you'll be treated to stunning visuals given how this movie has been graded. Add a sound mix that's an immersive, often swirling accompaniment and you'll be dredged in this peculiar world all the more.

Some might know this as Live, Die, Repeat, which perfectly describes the movie, this is one of the more underrated sci-fi stuck-in-a-loop movies I've ever seen –and the 91% Rotten Tomatoes score certainly concurs.

The 4K re-master brings a more contrasty yet detailed picture, with a bombastic Dolby Atmos sound mix that really elevates this movie experience to another level. It's a must-have for any movie collector.

One of Christian Bale's grittier roles, this psychological horror's glossy aesthetic is presented better than ever before in the 4K Blu-ray re-master.

It features a stellar ensemble cast – Willem Dafoe, Jared Leto, Reese Witherspoon, to name but three – in a melting pot of horror meets comedy like little else. It's witty, it's wry, it's as unmissable as it is disturbing.
