The Motion Picture Academy issued a statement Saturday calling Trump's executive order "extremely troubling" noting too that "Asghar Farhadi, the director of the Oscar-winning film from Iran 'A Separation,' along with the cast and crew of this year's Oscar-nominated film 'The Salesman,' could be barred from entering the country because of their religion of country of origin."
Their religion was not part of the executive order; only the country of origin.
More to the point, why was it okay when Obama banned Iraqi refugees for 6 months back in 2011 and Trump wants to do the same for half the amount of time? Nobody complained then after the press finally did its job and learned about it.
New Yorker writer and ultra liberal Philip Gourevitch wants an all-out Oscar boycott. "All of Hollywood should skip the Oscars out of solidarity until the ban is lifted," he tweeted.
But it's doubtful Hollywood can go without their narcissistic succor, and fear that nobody but themselves will care if they had the Oscars or not.
This said however, it's likely that Trump's immigration/refugee ban is not legal as Red State points out and "House of Cards" creator Beau Willimon tweeted about on Saturday: "The 1965 Immigration & Naturalization Act eliminated national origins as a basis for immigration."
Trump's argument is that national security overrides (or trumps) that law.
We will soon see how it all plays out.
