I sent the follow e-mail off to the SDCC:
My name is Anna Ath----, and I am attending San Diego Comic-Con. I am an enormous supporter of Torchwood and Doctor Who, two programs which air on BBC America.
Thousands of fans in America are anxious to see their favorite British actors at the Con, as these actors rarely attend events outside of the UK. An event like San Diego Comic-Con is the perfect way to bring these well-revered actors to the states, as it is such a widely publicized event.
It would be a treat to see any number of the actors associated with the two programs, including David Tennant (10th Doctor), John Barrowman, Gareth David-Lloyd (Ianto Jones), Eve Myles (Gwen Cooper), Naoko Mori (Toshiko Sato), Burn Gorman (Owen Harper), and Freema Agyeman (Martha Jones).
I already hope plans to bring these actors out are under way. I ask on behalf of thousands of other fans that you take this into strong consideration. Please respond back with any information you may receive.
If you'd like to contact important people at all, please send all emails to firstname.lastname@example.org, or look for more contact details at the official website. You can also send a quick e-mail to BBC America through their website, which I'm sure is also a big help. However, be respectful.
