 Jennifer Ehle (Lizzy Bennett) is a blonde. The dark hair she wears  during this production is a wig. Knowing she would be wearing a wig  for filming, Jennifer had her hair cut very short. This was a  problem for the stylists, who had to cover the wisps of blonde hair  that escaped from the back of the wig. They would have preferred her  hair to have been kept long, which is neater to cover.
