I just wanted to let everyone who is interested in this film know that the movie now has an official Web site, along with a complete trailer:
It looks quite authentic as a period piece, and although Sophia Myles is a very slim Isolde, the timeless beauty of her facial features is indisputable. Emily is right - she reminds me very much of the beautiful Kelsey Olson, or Kate Winslet in her younger years.
Oh, and be sure to select the "Large" version of the trailer, which is still quite small. The others versions are too tiny to see properly.
