Peggy Guggenheim: Art Addict was is a fascinating film I enjoyed on a quiet evening with a glass of vino. Peggy build one of the most unique and important collections of 20th century art throughout her lifetime. The collection can now be seen in Venice, Italy at the galery she established herself. I won't spoil the film too much but let's say Peggy was quite a character and it makes for an inspiring watch.
