One of the now time-honoured traditions of the Academy Awards is the 'class photo' - a brilliant show of awkwardness in which nominees gather to have their photograph taken like they've just graduated from primary school.

It's a great game of 'find-the-face-you-recognise'; with the photo hiding the likes of La La Land's Ryan Gosling and Emma Stone, Moonlight's Mahershala Ali, Loving's Ruth Negga, Jackie's Natalie Portman, and Manchester by the Sea producer Matt Damon.

Of course, there are some notable absences. Most importantly, celebrated Iranian filmmaker Asghar Farhadi, whose film The Salesman is nominated in the Foreign Language category.

For 90 days, visas would not have been issued to nationals from Iran, Iraq, Libya, Somalia, Sudan and Yemen. The Department of Homeland Security has since suspended all enforcement of Trump's immigration ban following a nationwide locking of the executive order from federal judge James Robart in Washington.

The 'class photo' was taken at the annual Oscars luncheon, which saw Cheryl Boone Isaacs address attendees about the politically charged nature of this year's ceremony.

"Each and everyone of us knows that there are some empty chairs in this room which has made academy artists [into] activists," she stated. "There is a struggle globally today over artistic freedom that feels more urgent than at any time since the 1950s. Art has no borders. Art has no language, and doesn’t belong to a single faith. No. The power of art is that it transcends all these things and strong societies don’t censor art; they celebrate it."

"America should always be not a barrier but a beacon. We stand up in support of artists around the world we stand up to those who would try to limit our freedom of expression and we stand up for this fundamental principle: that all creative artists around the world are connected by that unbreakable bond, and more powerful and permanent than nationality and politics. And just as our work does not stop at borders, borders cannot be allowed to stop any of us."

She also touched upon the Academy's role in setting the dialogue on diversity in film; with a new move following last year's controversial ceremony - in which, once more, all acting nominees were white - which saw the introduction of 683 new academy members, 46% of which were women and 41% people of colour.

"When we expand our membership, when we reach out to be inclusive, we set a shining example. When our storytellers tackle issues of importance from religious intolerance to racism to sexism … we become agents of change," she added.
