Samsung takes the now-familiar premise of the "unboxing" video to show far the brand's mobile technology has evolved over the years in this energetic, effects-driven film from 72andSunny and directed by Asif Mian and Bob Partington of 1st Ave Machine.

In the opening scene, a man opens a Samsung "shoe box" to reveal a gigantic mobile phone with a huge antenna, feeling its hefty weight in his hand. Via some dazzling VFX, he unpacks that, nesting-doll style to reveal increasingly smaller devices.

The spot goes on to capture Samsung engineers of the past, trying to conceive the perfect watch phone -- resulting in models that get more compact, sleek and cool with each iteration. a Other scenes show the brand reaching a high point, making the first 3G call from Mount Everest - and then a "low" one, under water, demonstrating the Galaxy S5's water-resistant capabilities.
