Source of Lung Problem.
Perhaps they shouldn't smoke.
Though it did appaer that Colin Farrell's character passed on his illenss to Selma Hayek's ( curing him. If that is possible.) and killing her off at the end.
I did notie that sometime in the begining of the film he coughed up some nod from his lungs, and so did Selma while getting ready to go to town to go to the movies.
Strange, I thought.
Perhaps it was something in the dust.
