I sent a LOR, one 5x7 photo, and a SASE to Hugh Bonneville via the Downton Abbey set address (no longer valid) in June/July and received a response today, December 4th, 2015, for a total of about 4.5-5 months.
His is the sixth response from out of ten cast members to whom I sent letters (the ones left are Maggie Smith, Brendan Coyle, Rob Jame-Collier, and Laura Carmichael). I'd been concerned about not hearing back but then they all started flooding in around October, so here's hoping that the rest will come through eventually as well!
Last five received: Seth MacFarlane, Oscar Nunez, Jesse Tyler Ferguson, Kenneth Branagh, Imelda Staunton
Most wanted: Neil Patrick Harris, Martin Short, Jim Rash, Charles Esten, Sara Bareilles, Josh Groban
