The reinvention of Jane Austen's 'Pride & Prejudice' sees a modern heroine, played by Jemima Rooper, threaten to ruin one of the world's greatest literary love stories.
Bored bank worker Amanda Price literally becomes lost in her favourite Austen book, after she finds a strange portal in her bathroom and swaps places with its heroine Elizabeth Bennet.
The DVD and Blu-ray license for 'Lost in Austen' has been agreed for 14 territories, including Australia and New Zealand with ABC, the US with Image Entertainment, in Germany and Austria with KSM and in Holland and Belgium with Dutch Film Works.
Tobi de Graaff, director of global TV distribution at ITV Global Entertainment, said: "It is a beautifully produced piece of high-quality television, combining fairy-tale romance with contemporary adventure, opening up new audiences to Jane Austen's brilliant work -- the perfect formula for TV escapism.
"We're looking forward to continued success with 'Lost in Austen' and the 2009 premiere of 'Wuthering Heights'."
Damien Timmer and Michele Buck, joint managing directors at Mammoth Screen, and executive producers of 'Lost in Austen', said: "Lost in Austen had a big impact on British viewers, but it's very gratifying that Guy Andrews' brilliant reinvention of 'Pride and Prejudice' has translated so well for the international market too."
'Lost in Austen' was produced by Mammoth Screen and co-funded by Screen Yorkshire and ITV Global Entertainment, which has a first-look distribution deal with the business.
