Sarah, I appreciate your feedback, but you don't mention a time-frame.
Did you wait, for example...2 months? 4 months? 6 months? .....before deciding that you would not get an answer?
The first time I sent a letter to Peter Falk (before we had this web site), I estimate that it took 6 months for me to get a reply. And when I did get the reply, it was individualized, and enclosed an autographed photo which I had not even requested.
Have you waited that long? Just curious. I think it largely depends on Peter's film-making schedule.
I don't know anything about the address or how it works, but did you enclose a SASE? His PR people might not respond otherwise. Just multiply the postage times hundreds or thousands of requests.
