Despite this production having received a number of poor reviews, it actually holds up quite well for its age. Note also that it is not a BBC programme, it was simply licensed to them by Granada Ventures when the Jane Austen collection was released on DVD.
So how does it compare with other adaptations of the same novel? The most well-known version these days is the 1995 film with Amanda Root as Anne Elliott and Ciaran Hinds as Captain Frederick Wentworth. That film was of course shorter but a good snapshot of the story - the earlier version, with Ann Firbank and Bryan Marshall in the same roles, had four hours to tell the story and moved at a more leisurely pace.
Firbank is a good ten years too old for her role, but she is very good - Marshall is excellent as Wentworth, a man disappointed in love, and bitter about interference. And hidden in the cast are people who also contribute - Michael Culver, later seen in Cadfael, as Harvill; Richard Vernon, later seen in the Hitchhikers Guide to the Galaxy, as Admiral Croft; Noel Dyson, earlier in Coronation Street, as Mrs Musgrove.
One criticism I do have is that the hairstyles are a bit distracting, and that the costumes are awful! Still, this shouldn't detract from a hugely enjoyable Austen adaptation.
