I read the book over the weekend, and by all accounts Virginia was sexy and sexual, rather flirtatious and outgoing. She even says that if she went out with a man, she slept with him. Many figures from their lives are combined and changed, but you can kind of tell where the writers have picked apart little details…

When Ethan and Virginia were having their pillow talk, she noted that he must have looked in Bill's private file.

Bill Masters was playing the wine glass out of boredom in the opening scene—his wife put her hand on his to get him to stop.
