Hot on the heels of the excellent Deepwater Horizon comes another true-life thriller from director Peter Berg and actor/producer Mark Wahlberg. This time around the focus is the 2013 Boston Marathon bombing and the subsequent manhunt for the two perpetrators of the incident.

The first Percy Jackson film was one of the better Harry Potter knockoffs, but we doubt many people spent the past three years hoping for a sequel. Still, that's what we've got – and what a feeble affair it turns out to be, lacking the sparky dialogue that kept viewers interested between the CG-heavy action scenes. It also struggles to convince as a 3D proposition thanks to how dull much of the movie looks; in 2D it seems rather more attractive. Fittingly, the disc's meagre extras are just as forgettable as the main feature itself.

After a spate of mysterious deaths in his home town, 13-year-old Mike (Michael Baldwin) becomes convinced that strange things are afoot at the local mausoleum. With the aid of his older brother Jody (Bill Thornbury) and friendly ice-cream seller Reggie (Reggie Bannister), Mike discovers that a mysterious undertaker he dubs the Tall Man (Angus Scrimm) is robbing graves and transforming the corpses into an army of murderous dwarfs. So begins a decades-spanning battle for the fate of our planet…

Sleepwalking during her first night at a boarding school in the 'Swiss Transylvania', American student Jennifer Corvino (Jennifer Connelly) witnesses the brutal murder of another girl. Fleeing the scene, she eventually ends up at the home of local forensic entomologist John McGregor (Donald Pleasance) and his chimpanzee attendant, Inga. Learning of her unique ability to telepathically communicate with insects, John asks Jennifer to use her unusual talent to help him catch the psychopath who has been butchering girls at the school.

A key film in the development of the romantic-comedy, this 1959 vehicle for Doris Day and Rock Hudson finds them lighting up the screen as an uptight career woman and the carefree playboy she is forced into sharing her telephone line with. While this new restoration does wonders for the film’s vibrant palette, the AVC 2.35:1 1080p encode is let down slightly by DNR (most obviously on the split-screen opticals).

Piranha 3D is the ultimate in cinematic guilty pleasures and marks a renaissance of sorts for director Alexandre Aja after the abysmal Mirrors. The plot is so thin that it’s barely worth mentioning. All that really matters is that it’s Spring Break at Lake Victoria, Kelly Brook and adult movie star Riley Steele are 'Wild Wild Girls!', the waters are full of barely-clothed teenagers and an underwater earthquake has unleashed a shoal of prehistoric piranha. What follows is a perfectly playful mix of sex and violence, unleashing both by the barrel-load but always remembering to smile at the same time.
