from your list I got Molly Shannon back, Amanda Peet didnt reply.

I got also Jason patric last week, so you might get him back. Still wating on Chris Noth.

Just to let u no my wife sent a index card to Sam Waterston and had a quick reply back (under 2wks) the index card was signed. he was in a play in the Us which is coming to Broadway.
she has just wrote to Jason Patric and Chris Noth who are on Broadway together. anyone got success from them?

my wife wrote twice also first just an index card the 2nd time was 2 5x7 photos no reply...

I sent twice to Zachary Quinto, once in September, never heard back. I sent again in December, addressing the envelope to the stage manager, and I received my item signed in January. Keep in mind that the second time I wrote I sent a photo of Zach and me that I'd had taken when I saw the play, so that might have influenced the response.

Eric Borgoson replied back to her

I sent a custom index card and a plain index card to all of them. Everyone signed both, although Jesse L. Martin was the only one to inscribed.

She got Molly shannon back..She has re-written to Jesse with a photo. can i ask did u send photos or Index cards?
I know sum stars wont sign index cards and prefer to sign photos mind you there are sum that wont sign photos and only sign index cards...weird

I had successes from Molly Shannon, Jeremy Sisto and Jesse L. Martin.

For the most part I keep my request strictly to Broadway. I feel I have the best chance of getting a faster, legit signature because the person in question is def. at that location to get the mail. Of the list you posted the only one I have tried was PeeWee Herman and I have still not heard back on that. I will say my very best success of all time was Cherry Jones from "24". I got several fantastic inscribed pics from her in a very quick turn around when she was doing "Mrs. Warren's Profession". I JUST tried Donnie and Marie Osmond during their Christmas show but have also not gotten anything back.
