I watched (IMHO canibalistic) movie "Seven Pounds" where protagonist donated many of his organs to other people and I noticed, that most recipients were black also as protagonist was.

Is race really taken into account when organ transplanting?

UPDATE

The question is not just about if interracial transplantation really good or bad. I can imagine, that transplantation is done same-race just in case, in favor of "do not harm" principle.
