I got a request last month to feature a female director.

Trouble is, there aren't many. It seems possession of a penis is almost mandatory before an individual is allowed to shout 'Cut' or 'Action'. And not just in commercials - it's the same in the world of feature films.

Why this should be, I don't know. If you have a theory, write it up as a comment. The best answer I can give is that you need to be part megalomaniac to want to direct, and just as history's foremost dictators have been men, so have the best directors.

But there is one very interesting director around right now who also happens to be female - Siri Bunford. Her 'Kubrick Season' promo has just been nominated for a D&AD pencil.

You've almost certainly seen it, and it is the best thing on her reel. If you like that, do watch the rest; it's in a similar vein. I met Siri in the flesh once, when she pitched for a Guardian ad when I was at DDB. Can't remember which one. But she had the same luminous intelligence in the flesh as comes across in her work.

Her sensibility is perfect for Channel 4, and arguably harder to apply to the rough-and-tumble world of product advertising. But if you have something that needs a bit of elegance and intelligence... I reckon you could do a lot worse than put Siri on it.
