Tom Baker's publicising an interactive sci-fi quiz DVD at the moment, which explains why he's doing a blog for Blockbuster. When I think of my childhood, and watching Dr Who from behind the sofa, it is Tom that I think of.
He is fixed in my mind in a way that David Tennant can never achieve. When I hear his voice, its like hearing my grandfather offering me advice. This is no doubt why he is heard as the voice over on so many British TV adverts, such as the current one for Duracell Batteries.
I can't think of another voice that has the same affect. There are other very recogniseable voices, like Brian Blessed, but they don't make me feel the same way.
Unfortunately the blog was only for a weekly entry during the month of November, so its now over.
