No one famous as such, but the actor Mark Frost, who I used to fancy years ago on the Bill and Doctors.
I have sent him several fan letters over the past two years requesting an autograph/signed photo but he never replies. I contacted his agents who said they passed on the letters but "he dosent do requests or replies".
On a horror film dvd I bought a while back on the extras the crew were laughing at him behind his back [he was being made up as a devil-like monster] because he was so pretentious and felt he was "all that".
Hes gone to look really old lately.
