Jennifer Love Hewitt is actually an avid fan of Audrey Hepburn and admitted she found it very "scary" to be playing her idol onscreen as she was worried her portrayal would not do her justice.
I would like to thank my mother, who taught me to stand up straight, sit erect, use discipline with wine and sweets, and only smoke six cigarettes a day.
The day Holland is liberated, Audrey was sick and almost died in the story. Later in the film she tells someone about that day and how wonderful it was to watch the movie in the middle of town to celebrate. She was too ill to get out of bed and would not have been able to attend.
A four-hour version was made for foreign distribution.
