This is the best ad of 2008 so far.

The Euro RSCG effort for energy firm EDF uses 100% 'recycled footage' - including shots of JFK, the Wombles and Thunderbirds - for an ad trumpeting its eco-friendly credentials.

I think it works rather well.

The idea is solid and yet lateral, and the execution is excellent. Cutting together such diverse bits of film to tell a coherent story... not as easy as they make it look.

Somewhere in the back of my mind I feel a bit uneasy that one of the country's biggest polluters is advertising how green it is. In the same way that Walkers talk about how healthy their crisps are, and in '1984' the interrogation centre was called the Ministry of Love...

But maybe that's just me.
