He adapted Helene Hanff's book "84 Charing Cross Road" for the stage. It was filmed in 1987, with Anne Bancroft, Anthony Hopkins, and Judi Dench. From the IMDb: "True story of a transatlantic business correspondence about used books that developed into a close friendship."

"Everybody associated with Hampstead Theatre will be saddened by the death of our first Artistic Director James Roose-Evans, who passed away peacefully on Wednesday at the age of 94. James founded Hampstead in 1959, and over 12 years in charge directed a huge range of work - including world premieres of plays by Pinter and Tennessee Williams – whilst ensuring its future by moving it to its first Swiss Cottage home and securing Arts Council funding. Over the years his counsel remained invaluable and the theatre stands as monument to his wisdom, his art, and his life."

What I posted in 2017:

He was a priest of the Church of England.
