The diabolical dr. phelbes -beautiful 1930s decor with all the classic Marcel Breuer furniture Lo strano vizio della Signora Wardh -very nice 1960s Italian modernist decor. Ciallo as a genre tend to have decent interior design. L'Amant -beautiful period Indochinese decor Fa yeung nin wa and 2046 by Wong Kar-Wai -Terrific 1960s Hong Kong decor. Always great details with erotic lightning Casablanca -many great ideas for bar designs, if you need ideas for a guy's den Amelie -Great French Country Metropolis (Fritz Lang) -Really nice machine age decor. Most of the rugs used exhibited avant garde designs which later were copied the world over Once upon a time in America Trilogy -so many great decor... Rock Hudson Movies -His movies are decent chick flicks but damn the mid-century decor is always top notch. I've visited his estate and the guy does have very good taste in his personal decor as well. There are so many more...do you have a specific period you like? I used to keep a list of movies with great decor for home improvement/remodeling efforts. My favorite periods are 1916-1919 and 1937-1940.
