Background: Lord Voldemort (;  in the films; born Tom Marvolo Riddle) is a fictional character and the main antagonist in J. K. Rowling's series of Harry Potter novels. Voldemort first appeared in Harry Potter and the Philosopher's Stone, which was released in 1997. Voldemort appears either in person or in flashbacks in each book and its film adaptation in the series, except the third, Harry Potter and the Prisoner of Azkaban, where he is only mentioned. Voldemort is the archenemy of Harry Potter, who according to a prophecy has "the power to vanquish the Dark Lord".
Context: Voldemort does not appear in Harry Potter and the Half-Blood Prince, although his presence and actions are felt: he once again declares war, and begins to rise to power once more. He murders Amelia Bones of the Department of Magical Law Enforcement, and begins to target members of the Order of the Phoenix, including Emmeline Vance.  Rowling uses several chapters as exposition to establish Voldemort's backstory. In a series of flashbacks, using the pensieve as a plot device, she reveals that Voldemort was the son of the witch Merope Gaunt and a Muggle called Tom Riddle. Riddle abandoned Merope before their child's birth, soon after which Merope died, just hours after giving birth. After living in an orphanage, young Riddle met Dumbledore, who told him he was a wizard and arranged for him to attend Hogwarts. Riddle was outwardly a model student, but was in reality a psychopath who takes sadistic pleasure in using his powers to harm and control people. He eventually murdered his father and grandparents as revenge for abandoning him. The book also discusses Riddle's hatred of "Muggles", his obsession with Horcruxes, and his desire to split his soul to achieve immortality. Rowling stated Voldemort's conception under the influence of a love potion symbolises the prejudicial circumstances under which he was brought into the world.  In the main plot of the book, Voldemort's next step is to engineer an assault on Hogwarts, and to attack Dumbledore. This is accomplished by Draco Malfoy, who arranges transportation of Death Eaters into Hogwarts by a pair of Vanishing Cabinets, which bypass the extensive protective enchantments placed around the school. The cabinets allow Voldemort's Death Eaters to enter Hogwarts, where battle commences and Dumbledore is cornered. Hogwarts professor (and re-doubled agent) Severus Snape uses the Killing Curse against Dumbledore when Draco could not force himself to do so.

Background: Manisha Koirala (born 16 August 1970) is a Nepali actress who mainly appears in Hindi films in India, though she has worked in several South Indian and her native country's films. Noted for her acting prowess, Koirala is the recipient of several accolades, including four Filmfare Awards--and is one of India's most well-known actresses. Although the box-office collections from her films have varied considerably, critics have noted that her niche as an actor remains unharmed irrespective of her commercial potency. She was one of the highest paid actresses in the 1990s.
Context: After receiving a diploma in filmmaking, she produced the small-budget caper-comedy Paisa Vasool (2004), in which she starred along with Sushmita Sen; this was probably the first ever chick-flick in Indian cinema in that it did not have a male lead nor a love story. Since then, she has played supporting and leading roles in various unsuccessful films, some of which being well received by critics, such as the historical epic drama Taj Mahal: An Eternal Love Story (2005), the thriller Tum - A Dangerous Obsession (2005), and the horror film Anjaane - The Unknown (2005).  In Anwar, she played a supporting role along with her brother Siddharth, her only release in 2007. In 2008, she made her comeback to films, with her first leading role since Mumbai Express (2005), in Tulsi, opposite Irrfan Khan. Although before release, her comeback was described by the media as "shocking", and the film suffered from poor marketing, her performance as Tulsi, a young homemaker diagnosed with leukemia, was well received. Taran Adarsh from IndiaFM wrote: "Manisha Koirala sinks her teeth in this role and delivers a fine performance." She next starred in Sirf (2008). The film was released without any notice or publicity and was a critical and box office failure. Her first Bengali film Khela, directed by Rituparno Ghosh, released the same year, along with the long delayed Hindi film Mehbooba, both films released on the same day.  In December 2009, she served as a Jury member in the fifth edition of the Dubai International Film Festival.

Background: John Milton Cage Jr. (September 5, 1912 - August 12, 1992) was an American composer and music theorist. A pioneer of indeterminacy in music, electroacoustic music, and non-standard use of musical instruments, Cage was one of the leading figures of the post-war avant-garde. Critics have lauded him as one of the most influential composers of the 20th century. He was also instrumental in the development of modern dance, mostly through his association with choreographer Merce Cunningham, who was also Cage's romantic partner for most of their lives.
Context: In 2012, amongst a wide range of American and international centennial celebrations, an eight-day festival was held in Washington DC, with venues found notably more amongst the city's art museums and universities than performance spaces. Earlier in the centennial year, conductor Michael Tilson Thomas presented Cage's Song Books with the San Francisco Symphony at Carnegie Hall in New York. Another celebration came, for instance, in Darmstadt, Germany, which in July 2012 renamed its central station the John Cage Railway Station during the term of its annual new-music courses. At the Ruhrtriennale in Germany, Heiner Goebbels staged a production of Europeras 1 & 2 in a 36,000 sq ft converted factory and commissioned a production of Lecture on Nothing created and performed by Robert Wilson. Jacaranda Music had four concerts planned in Santa Monica, California, for the centennial week. John Cage Day was the name given to several events held during 2012 to mark the centenary of his birth.  A 2012 project was curated by Juraj Kojs to celebrate the centenary of Cage's birth, titled On Silence: Homage to Cage. It consisted of 13 commissioned works created by composers from around the global such as Kasia Glowicka, Adrian Knight and Henry Vega, each being 4 minutes and 33 seconds long in honor of Cage's famous 1952 opus, 4'33''. The program was supported by the Foundation for Emerging Technologies and Arts, Laura Kuhn and the John Cage Trust.  In a homage to Cage's dance work, the Bill T. Jones/Arnie Zane Dance Company in July 2012 "performed an engrossing piece called 'Story/Time'. It was modeled on Cage's 1958 work 'Indeterminacy', in which [Cage and then Jones, respectively,] sat alone onstage, reading aloud ... series of one-minute stories [they]'d written. Dancers from Jones's company performed as [Jones] read."
