Impressive feat of compositing

Okay, so I'm a sucker for kitties. So when The Moving Picture Company, a post-production house based in Soho, London, posted its work on a new ad campaign for a UK dairy company, I had to check into it.

Wow. The first Cravendale ad packs a whole lot of artistry and creative genius into what you as the viewer don't see.  They make the kitties in this spot look pretty darn realistic. And without a single computer generated effect.

Since the spot was composited entirely from live-action plates, I can't begin to imagine the herculean feat required for pre-production.  Hats off to you, guys. Impressive!
