That Hamilton Woman

In 1941, Vivien Leigh (Scarlet) and Laurence Olivier (Mr. Darcy) starred in That Hamilton Woman, a film directed by Alexander Korda about the mistress of Vice Admiral Lord Nelson, who died in the Battle of Trafalgar in 1805.
Vivien was filmed in the poses of George Romney's portraits of the real Emma, which, along with her reputation as the mistress of a powerful man, made her famous. I found these side by side images of Vivien and Emma by Jean-Pierre Gueroult on Flickr.
