It would appear that this terrific video has actually been doing the rounds for some time, but despite the fact that it's a little on the 'mature' side, and even though it technically doesn't qualify as a viral advertising campaign - the brand of cheese in this video is fictional - I couldn't resist posting this.

Shunning the trend for CGI, animatronics expert John Nolan put together this mini-masterpiece for fun (and probably to showcase his not inconsiderable skills.... which I guess makes it a viral after all! Yay!). 

While audiences - and box office records - have been blown away by the remarkable visuals on display in Avatar, many have been left massively underwhelmed by its storytelling. In direct contrast comes this low budget video - a funny, heart-warming and ultimately redemptive story of an everyday mouse, in a gripping tale of triumph over adversity. All in under 90 seconds.

Eat your heart out James Cameron.
