That something extra, I believe, is a certain humanity that comes from upbeat and positive human interest letters and success stories. Advertisers like to be associated with those qualities.
I loved doing all those costume dramas. I didn't think, 'Ooh I've got to avoid being typecast' - you can't ever be dictated to by what other people think. I just do things because I fancy the parts and the directors.
The best way in the world to advertise is to get somebody else to run around with the name of your product on their person or showing it around somewhere and not only that but they're paying for it.
