(via) AdFreak has this to say:

Best ad of the year so far? It just might be this brilliant five-minute-plus spot by BBH London, in which Robert Carlyle, in a single continuous take, narrates the progression of Johnnie Walker whiskey from the backroom experimentation of a humble shopkeeper to the multinational powerhouse it is today. The combination of bagpiper abuse, well-timed visual cues, pitch-perfect writing and music, and Carlyle's charisma keeps the mini-movie chugging right along.

Not sure why it's subtitled in English (can people really not understand a bit of Scottish burr?), but what the hey?
