The cinematography is lush and sweeping, showcasing high-production values and elaborate period costumes.

Released at the height of Moore’s career, the film was a major "prestige" vehicle for her.

The 1995 adaptation of The Scarlet Letter is widely remembered more for its departures from Nathaniel Hawthorne’s classic novel than for its adherence to it. Often described as a "freely adapted" version, it reimagines the story as a high-stakes romantic drama. 🎬 Film Overview Roland Joffé Stars: Demi Moore, Gary Oldman, Robert Duvall Genre: Period Drama / Romance Runtime: 135 minutes 📌 Key Highlights The Scarlet Letter (1995) [720p] [BluRay] [YTS.MX]

Clear your Explorer thumbnail cache (see above) or copy the file to a different location.

This is a bug in Windows 10 that also affects other thumbnails – for example transparent PNG images here and here.

I can’t do anything in my program to work around it, I’m afraid. Please use the Windows 10 feedback function to report this to Microsoft. If enough users do it, they may eventually fix it. Windows 7 does not have this bug.
