Wanted: cast address(es) for 'Dexter' tv show

[Larisie]

As far as I know, otherwise those successes people get from TV sets a year or two later wouldn't make any sense if they didn't hold onto them. You should be fine sending now, especially if its been said they'll film soon!

"Dexter"
Sunset-Gower Studios
1438 N Gower St
Hollywood, CA. 90028

(Most indoor scenes are shot here)

I am somewhat new here so I was wondering if I have a cast photo already signed by one of the cast (Julie Benz) should I send the photo in one SASE addressed to a cast member at the above address, have it returned and keep doing that until they all sign? Or is there a way to send it to the address above once and have all the cast members in the photo to sign it?

Thanks!
