The following people have worked with both Klaus and Nastassja Kinski. Note, the list is not intended to be exhaustive, and I’ve generally stuck with actors people might know. I also am aware that Christopher Lee and Klaus Kinski appeared in the same film on at least five occasions. This is just a bit of fun. The only director offhand that worked with both was James Toback on Love & Money and Exposed respectively.
