You haven't explored Dickens fully ,,,,
until you have seen some of the Dickens' dramatizatons, especially those made by Masterpiece Theatre. However, some older ones in B&W are great because of the actors/director in the film versions. The two David Lean produced in the late 1940s, Oliver Twist and Great Expectation, are exceptional with a heavily made up Alec Guiness as Fagin. John Mills as a grown up Pip is unforgetable. Pip's friend, Herbert Pocket, is a not so made up Alec Guiness. Jeanne Simmons, in one of her first roles, is a memorable Estella when she humiliates Pip when he comes to play at Miss Haversham's.
And who can forget Ronald Coleman as the dissolute Sydney Carton. He is so good that you don't mind the Bastille made out of paper maiche.
In the twilight of his career, Alec Guiness portrays Little Dorrit's father who is condemned to spend his life in a debtor's prison. Diana Rigg is the haughty, but beautiful, Lady Dedlock of Bleak House. In another black & white movie, Allister Syms is the best ever Scrooge.
All of Dickens' novels plus a Christmas Carol have been dramatized with the exception of Barnaby Rudge and Dombey & Son. See the movies, then read the book. Dickens novels are not mysteries!
