The start of a new school year is a stressful time for kids all over the world - none more so than those who know their daily environment isn't safe. That's the reality for schoolchildren in America, who face regular active shooter drills and are taught to anticipate the possibility of being mown down by automatic gunfire on any given Tuesday.

The Sandy Hook Promise - founded after the 2012 Connecticut massacre - draw attention to this barbaric situation with a new, deeply disturbing and emotionally challenging campaign. Initially appearing to be a typical 'back to school'-style ad, things quickly devolve into showing the reality of what attending school in the US means.

As craft supplies are re-purposed as makeshift weapons and children attempt to run and hide, the fact suggested restrictions on guns are invariably rejected feels unbearably bleak. Schools will redesign their corridors to brace for the inevitable, yet lawmakers won't intervene. This affecting film is a stark reminder of that 'new normal' - one which cannot be allowed to become normalised any further.

The world takes on a fantastically elastic quality in this whimsical commercial for Lego. The surreal film sees a hunter attempting to keep up with his prey... with only an oversized bow and arrow for company. Fear not, younger viewers, as there's never any suggestion that his furry little opponent is in danger. Instead, the rowdy rabbit manages to outwit him at every turn.

Lively production design will satisfy young and old alike, with bright colours and constantly-morphing characters grabbing attention while nostalgia runs through each iconic Lego piece (the flames are a particularly nice touch). Madcap and eccentric, directors Traktor have constructed a worthy tribute to the ubiquitous toy.

This poignant outing for Vodafone's New Zealand arm explores just one way 5G can make the world a better place. With greater connection comes an easier sharing of resources - something an elderly gent finds out the hard way when his beloved pooch falls ill.

There's a lovely stillness to this film, as subdued family time with the sickly dog and his struggling owner is interspersed with shots of a man trying to navigate rainy city streets in a hurry. The connection isn't immediately clear, but the emotional tone of the film leads us to trust that there's hope on the horizon.

While the old man/sick pet trope is a familiar method of tugging on an audience's heartstrings, the lovely performances from the family mean we feel genuine relief when it's revealed that Huxley has, in fact, made it - thanks to a surgeon able to dial in remotely via the advertised network. Charming work which uses all of its 120" runtime for maximum emotional pay off.

Nike's latest addition to their 'Dream Crazier' strand focuses on tennis players Caroline Garcia, Simona Halep, Madison Keys, and Elina Svitlona as they each describe how to cope with cynics and haters. As director Stefan Hunt's film shows, it can be done with a light touch.

The international quartet are well cast, as they challenge preconceptions about size, character, and "ladylike" behaviour on the tennis court. Despite the high stakes, there is still room for the odd trick shot or wink to camera.

Such moments are playfully enhanced by hand-drawn animation, including Keys's run-in with a pesky fly. Rather than detract from the players' statements, these moments ensure a winning blend of the bold and the light-hearted.
