Crisp, who once described himself as "The Stately Homo Of England", died in 1999 at the age of 90. So it's always possible that Hurt could reprise the role one last time to cover the last years of Crisp's life. And by doing so, would make the televersion of Quentin Crisp eligible for membership in the TV Crossover Hall of Fame for the three related projects.
Here's a VERY short profile of Quentin Crisp:
Quentin Crisp was Oscar Wilde's perfect descendant. With his calculated caustic words, open homosexuality and wittily provocative attitude toward any kind of conventionality, Crisp caused a bit of a stir in conservative England during the 1950s and 1960s, and even on through the 1970s. In 1981, Quentin Crisp moved to New York City, bringing along his familiar and witty remarks and his eccentricity. Quentin Crisp charmed everyone and became "the face of a modern rebel."
Throughout his near twenty-year tenure on Manhattan, Mr. Crisp wrote a variety of books, reviews, appeared in several movies (most notably playing Elizabeth I in Sally Ann Potter's Orlando) and otherwise delighted us publicly and privately with his inimitable grace, wit and genius. Quentin Crisp died on the eve of touring his one-man show in Manchester, England, on 21 November 1999.
