[quote="HappinessStan"]You're more likely to get a success by writing to the agency addresses on the database, or the Glasgow Doctor Who address

from the BBC website

"Where can I send fan mail or personal letters to?

You can send mail to Matt Smith at the address given above. The Doctor Who actors are usually responsible for handling their own correspondence; however we are able to forward any fan mail to them on your behalf. If you wish for us to do this for you, they can be reached at the following address:

(Name of celebrity)
Doctor Who
c/o Artists' Mail
PO Box 1922
Glasgow
G2 3WT

Please write 'Private and Personal - Please Forward' at the top of the envelope."

Most Dr Who actors, past and present (with some exceptions) are very good with fanmail. Good luck.[/quote]
