Though it might not be considered violent compared to many thrillers, the acting, casting, and dual-story plot make this one of the most intriguing thrillers I've seen in a while. There is a subtle interweaving of stories fom the Dickens manuscript and the modern-day murder case-- some actors play double roles, which adds to the supernatural quality of the mystery.
This film does draw very loosely on events in Dickens' life and marriage, though it "re-writes" much. More interestingly, it brings out the darker side of the Victorian author's work with quotes from Oliver Twist, reference to the murders in Our Mutual Friend, and an almost Poe-like narration of a tale of madness and murder.
Derek Jacobi is versatile as ever, portraying both an insane (though well-read) homeless man, and the author/narrator of the newly discovered Dickens manuscript. Mel Smith (The Princess Bride, Alas Smith and Jones, Trevor Nunn's Twelfth Night)has a brief but amusing appearance as the enthusiastic (and athsmatic?) authenticator of the manuscript.
Not big on action, but definitely worth watching for the sake of a good story. An added bonus is that, unlike the young and beautiful Hollywood sterotypes we are so familiar with, this cast can really act.
