Last filmed in 1988, Little Dorrit offers material--about greedy lenders and eager investors--ripe for reinterpretation. If the series doesn't surpass Bleak House, a high-water mark in Dickens adaptations, screenwriter Andrew Davies still does the author proud, despite a sketchy subplot concerning a miserable maid and her mysterious protector. But some things never change, and Dickens presents ample scene-stealing opportunities, of which Amanda Redman as a chilly socialite, Pam Ferris as a shallow governess, Russell Tovey as a lovesick suitor, and Andy Serkis as a Gallic psychopath--his creepiest character since Gollum--take full advantage. In the featurette, cast and crew provide a perceptive look at the making of this timely drama. --Kathleen C. Fennessy
