Great Expectations (1946 film) in Dickens' novel. The unit for the location work for the film was based on a derelict naval fort on Darnett Ness Island in the River Medway. The script is a slimmed-down version of Dickens' novel. It was inspired after David Lean witnessed an abridged 1939 stage version of the novel, by Alec Guinness. Guinness had played Herbert Pocket, and Martita Hunt was Miss Havisham in the stage version of 1939. The script for the film was written by David Lean, Anthony Havelock-Allan, Cecil McGivern, Ronald Neame and Kay Walsh. David Lean approached Clemence Dane to write the script, but
Monks (Oliver Twist) to outwardly be associated with any form of crime (this is not because he is a moral being, but because he fears being caught). Dickens keeps his motives and his true identity a total secret until nearly the end of the novel, thus surprising the reader with an unexpected revelation that adds complications to the plot. Monks does not appear at all in "Oliver!", the musical adaptation of the novel, nor in several film versions of the novel which seek to simplify the story, including Roman Polanski's 2005 adaptation of "Oliver Twist". He does, however, appear in several mini-series versions
