In the quarter of a century since Suzuki Koji's horror novel Ring was first published his story has spread as rapidly as the tale's cursed videotape. From film and TV adaptations to a multitude of sequels and even a crossover with the similarly long-haired ghoul from The Grudge, Koji's story keeps being reinvented for new audiences.

With a story that brings together Santa Claus, the Easter Bunny, Sandman, the Tooth Fairy and Jack Frost to do battle with Pitch Black (aka pitch, aka The Boogeyman), Rise of the Guardians is essentially the Avengers Assemble of seasonal movies.

Brazilian director José Padilha had a thankless task ahead of him when it came to remaking RoboCop. Mixing together shocking violence and worryingly prescient satire, Paul Verhoeven's peerless 1987 original is regarded as a classic by the majority of film fans, making the very notion of a remake even more redundant than usual. But despite having all of the odds stacked against it, this film more than justifies its existence with some big ideas of its own.

Timed to coincide with the cinema release of the remake, this new hi-def outing for Paul Verhoeven's satirical sci-fi masterpiece is a must-have for fans. While the DTS-HD MA 5.1 soundtrack hasn't changed, the disc's AVC 1.85:1 1080p encode (based on a new 4K remaster) is brighter, punchier and altogether much more impressive than the dull imagery seen on the original disc. And unlike its barebones predecessor this 2014 platter also ports over the majority of the extras from MGM's old Special Edition DVD and finds space for a new 42-minute Q&A with the filmmakers, recorded last year.

What's not to love about a musical based on '80s hair metal and power ballads? Quite a lot as it turns out – especially when so many of the songs are given over to a pair of charisma-free leads who would look more at home on the Mickey Mouse Club. Only Tom Cruise's electrifying turn as rock star Stacee Jaxx makes this remotely worth bothering with. As you'd expect, it looks wonderfully gaudy in hi-def and the DTS-HD MA 5.1 rocks. A selection of additional featurettes about the bands behind the songs prove far more interesting than the movie itself.

In the 'not too distant future' of 2018 the world is ruled over by giant corporations and the population is gripped by a popular and bloodthirsty new mix of roller derby and gladiatorial combat called rollerball. However, when champion player Jonathan E. (James Caan) threatens to become too popular and powerful, the secret cabal that runs the sport decides it's time to make an example of him.

A small group of highly skilled mercenaries are brought together in France by an Irish operative to steal a mysterious briefcase. What follows is a modern action classic of the kind they sadly don't make any more…
