Although this BBC production of "Martin Chuzzlewit" from 1994 is not widely known, it is definitely a very good one. The characters are true to Dickens' novel, some of them being rather multi-layered, such as the bitter and twisted Jonas Chuzzlewit, very well portrayed by Keith Allen, or the desperate young Martin Chuzzlewit (Ben Walden), who from his very first scene casts a spell with his eyes and voice.
For those BBC drama collectors who consider buying the video: This is not as light as the fine Jane Austen film versions, but rather dark and gloomy. In my view this contributes to the film's attraction, and I can recommend "Martin Chuzzlewit" without hesitation.
A piece of advice concerning the videotape: Watch it as soon as you purchased it because there are some tapes on which visual noise appears every now and then. You might perhaps have to exchange it.
