I seem to find that Gradepoint is filming on Vancouver Island, British Columbia, Canada. I was unable to find a specific address, but if someone could please find that address, it would really help. It sounds like they will be filming from late January to April or May. I don't want to missed this opportunity with David Tennant so close, and less expensive. Thank for any help you can impart.

Hey Laura, I live in the US and got a response from Tennant when I wrote to him. Don't worry, it's quite easy! Just go on eBay and buy some Royal Mail UK stamps. Lots of sellers have them (and ship to the US).

I was looking for this too! In order to get Tom Baker I bought doctor who stamps since they cost about the same as other uk stamps I even went through and wrote the royal mail it's very hard to get uk postage! I know they are in Canada right now not far from me I'm ready to take a drive! LOL

If anyone has or can find the address to write to cast members of the new show "Gracepoint", please, please let me know. I live in the US and this may be my only chance to get a response from David Tennant short of somehow getting some British money for return postage from the UK. I know they start filming soon/might already be filming, so soner than later would be very much appreciated.
