Document 2: Spetters: "Spetters" led to protests about how Verhoeven portrayed gays, Christians, the police, and the press.

Despite the large amount of controversy surrounding it, the film proved to be popular, with 1,124,162 admissions in the Netherlands alone.
Document 3: Spectre (2015 film): Spectre has received mixed reviews, with many reviewers either giving the film highly positive or highly negative feedback. Many critics praised the film's opening scene, action sequences, stuntwork, cinematography and performances from the cast. In some early reviews, the film received favourable comparisons with its predecessor, Skyfall. Rotten Tomatoes sampled 274 reviews and judged 64% of the critiques to be positive, saying that the film "nudges Daniel Craig's rebooted Bond closer to the glorious, action-driven spectacle of earlier entries, although it's admittedly reliant on established 007 formula." On Metacritic, the film has a rating of 60 out of 100, based on 48 critics, indicating "mixed or average reviews". Audiences polled by CinemaScore gave the film an average grade of "A−" on an A+ to F scale.
Document 4: Spectre (2015 film): Christopher Orr, writing in The Atlantic, also criticised the film, saying that Spectre "backslides on virtually every [aspect]". Lawrence Toppman of The Charlotte Observer called Craig's performance "Bored, James Bored." Alyssa Rosenberg, writing for The Washington Post, stated that the film turned into "a disappointingly conventional Bond film."
Document 5: Into the Gauntlet: "Into the Gauntlet" begins as Amy and Dan Cahill enter a London hotel tired and with no lead whatsoever. They receive another lead, but this is stolen by Isabel Kabra via a pet monkey, who leaves them a coin with a fancy script K on it. However, Dan, who has already memorized it, rewrites it. Amy looks all over the Internet to find out what it means, and she is about to shout out when Nellie realizes that the Kabra coin is a bug. She destroys it, along with three other bugs from each of the other three branches. Amy then tells them that the clue leads to William Shakespeare, so they go to a performance of Romeo and Juliet in The Globe Theatre. Once there, they confront the Starlings, who are back in the clue hunt after being sent to the hospital in an explosion back in "The Maze of Bones", and steal their lead, but they are trapped by Jonah Wizard, who was forced back into the clue hunt by Cora Wizard, the Holts, Alistair Oh, and the Kabras. Hamilton Holt steals the piece of paper with the lead, but Dan rips off the top and bottom, and he and Amy run away while everyone else is fighting over the rest of the lead. Their section of the lead says: "For this great man we sing was b here". The rest of the word that goes with the letter "b" was torn off, so they assume that it was supposed to be "born".
Document 6: Central Board of Film Certification: The Board consists of 25 other non-official members and a Chairperson (all of whom are appointed by Central Government). Prasoon Joshi currently presides the board, being appointed as the 28th Chairperson of the Board on 11 August 2017, after the ouster of Pahlaj Nihalani, who was preceded by Leela Samson who had resigned after the CBFC's rejection of a certificate for the film MSG: Messenger of God was overturned by an appellate tribunal. Earlier, Leela Samson had succeeded Sharmila Tagore, who was the longest continuous running Chairperson in the history. Nihalani was the 27th Chairperson after the Board's establishment. His appointment was highly controversial given his propensity for censoring films instead of merely certifying them.
Document 7: Spectre (2015 film): Whilst filming in Mexico City, speculation in the media claimed that the script had been altered to accommodate the demands of Mexican authorities—reportedly influencing details of the scene and characters, casting choices, and modifying the script in order to portray the country in a "positive light"—in order to secure tax concessions and financial support worth up to $20 million for the film. This was denied by producer Michael G. Wilson, who stated that the scene had always been intended to be shot in Mexico as production had been attracted to the imagery of the Day of the Dead, and that the script had been developed from there. Production of Skyfall had previously faced similar problems while attempting to secure permits to shoot the film's pre-title sequence in India before moving to Istanbul.
Document 8: Now You See Me (film): A year later, the four have their first major performance as the Four Horsemen in an elaborate Las Vegas show funded by insurance magnate Arthur Tressler (Michael Caine). Their final trick appears to transport one of the audience members to the vault of his bank, the Crédit Républicain in Paris, where stacks of new euro bills are stored. At the magicians' command, the fans in the vault activate, drawing the bills into the vents and then showering the Las Vegas crowd with them. The euros are shown to be real, and the vault in Paris is found to be empty of its recent shipment of euros. FBI agent Dylan Rhodes (Mark Ruffalo), and Interpol agent Alma Dray (Mélanie Laurent), are then partnered to investigate the Horsemen. The two question the magicians but have no evidence to hold them. Dylan and Alma turn to Thaddeus Bradley (Morgan Freeman), a former magician who now makes money by explaining the tricks behind magic acts. Thaddeus demonstrates how the Horsemen used a mock vault under the Las Vegas stage and says that the group must have stolen the money in Paris before it arrived at the bank, replacing it with flash paper that left no evidence.

Document 13: 2008 Summer Olympics torch relay: Some advocates for Tibet, Darfur, and the spiritual practice Falun Gong, planned to protest the April 9 arrival of the torch in San Francisco. China had already requested the torch route in San Francisco be shortened. On April 7, 2008, two days prior to the actual torch relay, three activists carrying Tibetan flags scaled the suspension cables of the Golden Gate Bridge to unfurl two banners, one saying "One World, One Dream. Free Tibet", and the other, "Free Tibet '08". Among them was San Francisco resident Laurel Sutherlin, who spoke to the local TV station KPIX-CBS5 live from a cellphone, urging the International Olympic Committee to ask China not to allow the torch to go through Tibet. "Sutherlin said he was worried that the torch's planned route through Tibet would lead to more arrests and Chinese officials would use force to stifle dissent." The three activists and five supporters face charges related to trespassing, conspiracy and causing a public nuisance.
