It depends which kind of movie you are looking for.
I would recommend:
The Pianist
Schindler’s List
The Thin Red Line
Der Untergang

Digging The New Look on Apple TV. A series about how Christian Dior and Coco Chanel, Pierre Balmain, and Cristóbal Balenciaga navigated World War Il and launched modern fashion.
