The Venice Film Festival ended with a bang of star power in the form of Mick Jagger and Donald Sutherland, who journeyed to the Lido on Saturday to promote the closing film from director Giuseppe Capotondi,\u00a0The Burnt Orange Heresy. The two stars quickly turned political when they were asked to comment on a peaceful demonstration that overtook the red carpet in front of Venice\u2019s main venue, the Palazzo del Cinema, earlier in the day. Hundreds of activists took to the festival to protest climate change, anti-immigration policies and Venice\u2019s\u00a0cruise ship problem. \u201cI\u2019m absolutely behind that,\u201d said Jagger unequivocally of the protest. \u201cI\u2019m glad they\u2019re doing that because they\u2019re the ones who are going to inherit the planet.\u201d Jagger blasted Trump for pulling out of the Paris Agreement. \u201cWe are in a very difficult situation at the moment, especially in the U.S., where all the environmental controls that were put in place \u2014 that were just about adequate \u2014 have been rolled back by the current administration so much that they are being wiped out,\u201d he said. \u201cThe U.S. should be the world leader in environmental control but now it has decided to go the other way,\u201d Jagger added. Sutherland concurred. \u201cMick is right when he said the reforms that were instituted during the Obama administration were barely adequate, and now they\u2019re being torn about." \u201cIt's the same in Brazil and they will be torn apart in England,\u201d said Sutherland of administrations under Jair Bolsonaro and Boris Johnson.\u201cThey have to fight harder,\u201d said Sutherland of his support of the red carpet protestors. \u201cAnd they have to get as much support as they can among all of you.\u201d \u201cWhen you\u2019re my age, when you\u2019re 85 years old and you have children and grandchildren, you will leave them nothing if we don\u2019t vote those people out of office in Brazil in London in Washington,\u201d continued Sutherland. \u201cThey are ruining the world. We have contributed to the ruination of it, but they are ensuring it.\u201d On another subject, acting versus touring, Jagger said that although they\u2019re both ways of performing, there are big differences. \u201cOne, if you make a mistake on the stage, if you fall over, you don\u2019t get a retake. If you fall over in the film, it\u2019s fine," he joked. \u201cIt\u2019s a different part of your brain that is activated in acting, which I do very rarely,\u201d he added. \u201cI enjoy doing it.\u201d \u201cAs an actor your role and part is to put on a mask,\u201d he said. \u201cYou may want to put on several masks. Or you may want to take some of them off and reveal some of yourself. As a writer you want to create lots of illusions and lots of characters. I guess that\u2019s some kind of mask.\u201dJagger said what attracted to him about his role in the\u00a0Burnt Orange Conspiracy, playing a fabulously wealthy art dealer and collector, was the fine line between truth and falsehoods, and that the audience never really knows who is lying. \u201cIt\u2019s very much of this modern dialogue,\u201d he said about how current politicians operate. Jagger added, \u201cWe are going through a very strange time at the minute. And when you live at a strange time you know it\u2019s a strange time but you don\u2019t know what\u2019s going to happen. Values are different.There\u2019s more polarization and less civility.\u201d On "civility," a loaded term in the U.S., he said, \u201cI\u2019m not sure I was always against civility, but when you see it now the incivility of political life which we see in so many countries including my own, especially this last week\u2014 and in other countries, particularly the U.S.\u2014 when you see this, it\u2019s a bit of a sea change from what you were used to,\u201d referencing Johnson and Trump\u2019s continued public attacks against critics. \u201cI don\u2019t mean that manners are everything. But the combination of all these things, where it\u2019s going to lead us,\u201d he added, is \u201cpolarization, rudeness and lying.\u201d Sutherland, who plays the reclusive painter Jerome Debney, called\u00a0Orange Heresy, \u201cthe best script I\u2019d read in 20 years.\u201d Claes Bang plays an ultra-ambitious art critic who is hired by Jagger\u2019s collector to interview and secure a painting from Debney, who hasn\u2019t showed his work to anyone in decades. Elizabeth Debicki co-stars as Bang\u2019s American love interest. Bang commented on the role of criticism today. \u201cI fucking hate getting bad reviews but it\u2019s part of the business,\u201d he said. \u201cEverything is sort of moving in that sense.\u201d Jagger spoke about his own role as an art dealer and collector: \u201cHe wants to hype his gallery up. The art world has all these, not just artists but people that hype the artists and make their art more valuable than other artists. How does this work? A lot of time it\u2019s hyped by dealers. Why not? The artists then gets paid and everyone gets more money.\u201d The rock legend said that it wasn\u2019t a role he readily identified with. \u201cI'm not really a collector. I throw things away,\u201d he said. \u201cI buy things and then lose them. I\u2019m a completely hopeless collector. I\u2019m the complete opposite.\u201d The Burnt Orange Heresy\u00a0premieres out-of-competition Saturday night in Venice. This article originally appeared in The Hollywood Reporter.
