correct tags?

Because i'm not a natural speaker of the english language i've some problem finding the right word/phrase. Perhaps someone could correct my suggestion for the following tags:

# a book which becomes a movie: "picturized"
# a movie which story is out of a book: "based on a book"
# a movie which story is out of a comic: "based on comic"
# a movie which story is out of a videogame: "based on a game"

by the way... it would be very nice if some more of you would tag their collection items. It's quite a interessting possibility to find new movies/books.

for example:
www.listal.com/search/dvds/1/?tag=zombies
;-)

The first two seem to be saying the same thing; "based on a book" is fine, and doesn't need changing, but you might want to consider "adaptation", or "dramatised", perhaps. All the other phrases are perfectly accurate and say what you want them to, 100% clear :-)
