The Accuracy of Argo

Last week Mr. O'Connor brought up an interesting fact about the movie Lincoln. O'Connor announced that Lincoln knowingly expresses misleading information. In the movie, it supposedly states that Connecticut voted against the 13th Amendment, while in reality Connecticut was in favor for it. Just as Lincoln displayed false information, the movie Argo did as well. 

According to this interview on CNN with Jimmy Carter, Carter states, "that ninety percent of the contributions to the ideas and the consummation of the plan was Canadian, [however] the movie gives almost full credit to the American CIA".

First off, I understand that directors choose to "alter" aspects of history in order to add drama, however, I wonder to what degree is it considered ok for directors to knowingly change facts of history?

To add, I also find it interesting that, as Carter mentioned above, the directors of Argo chose to give credit to the Americans, rather than the rightfully deserved Canadians. Did the directors choose to divert the attention to the American CIA for merely the affect of drama? Or are Americans not inclined to watch a film where they are not shown in the most positive light possible?

This reminds me of another discussion we had in the beginning of the year about how the government chose to only show clips of the Vietnam war that illustrated progress and success, instead of showing that there was very little progress or success actually being made. Just as the U.S. government chose to not tell the whole truth, do you think the film-makers of Argo had the right to stretch the truth in order to appeal to the audience, why? If you were the director of Argo would you have chosen to do the same thing?
