You can get Lord of the Rings movie prop/costume cards (eg. a piece of Frodos cloak) or Terminator 2/3 cards have pieces of Arnies leather jacket as well.
doubt i'd collect them myself, but the kiss cards are a clever concept
some feature film relics would be kinda funky
say a piece of endoskeleton from a terminator film
or umm... a piece of the big kahuna burger or a red apple cigarette from pulp fiction
a piece of the stupid yin yang table or some homemade soap from fight club!!
