I'm a big fan of John Le Carre's writing and I enjoy watching each adaptation as they come along. The Night Manager is a gorgeous production that differs from the book in many ways but is still very much in the spirit of the book.
I've read The Night Manager twice and the novel really has some problems - the long section in Canada is really tedious, and the Caribbean/Central America setting is pretty cheesy. The adaptation actually improves on the book and, I should add, Le Carre loved the adaptation. Fabulous cast and briliiantly acted. Tom Hiddleston, Elizabeth Debicki, Hugh Laurie, Tom Hollander, David Harewood, Olivia Colman and others, they're all perfect.
