USA Today initially reported that Michael Moore will be screening his new film SiCKO at a Tehran film festival in October. Alas, one of Moore's producers responded with an even-tempered denial (which was dutifully reported by USA Today).
That's a shame.
With the help of a beautiful and intelligent attorney, I uncovered a Treasury Department guide to U.S. sanctions against Iran. Officially speaking:
The receipt or transmission of postal, telegraphic, telephonic or other personal communications, which does not involve the transfer of anything of value, between the United States and Iran is authorized.
I'd say that gives SiCKO the green light.
