"May Jonathan Frid, 'our reluctant vampire,' live on in our hearts!" Frid's co-star, Kathryn Leigh Scott

, wrote on her website. "How blessed I am to have known this dear man and to have such wonderful memories of him, both on screen and off. ... He was irascible, irreverent, funny, caring, lovable and thoroughly professional, and in the end became the whole reason why kids ran home from school to watch Dark Shadows."Before his death, Frid, who also starred in the TV movie The Devil's Daughter and the horror film, Seizure, filmed a cameo appearance for Tim Burton's forthcoming big-screen remake of Dark Shadows, in which Johnny Depp will play Barnabas.
