Question:
Tristan Tzara (French: [tRista dzaRa]; Romanian: [tris'tan 'tsara]; born Samuel or Samy Rosenstock, also known as S. Samyro; April 16 [O.S. April 4] 1896 - December 25, 1963) was a Romanian and French avant-garde poet, essayist and performance artist. Also active as a journalist, playwright, literary and art critic, composer and film director, he was known best for being one of the founders and central figures of the anti-establishment Dada movement. Under the influence of Adrian Maniu, the adolescent Tzara became interested in Symbolism and co-founded the magazine Simbolul with Ion Vinea (with whom he also wrote experimental poetry) and painter Marcel Janco. During World War I, after briefly collaborating on Vinea's Chemarea, he joined Janco in Switzerland.
Tzara was born in Moinesti, Bacau County, in the historical region of Western Moldavia. His parents were Jewish Romanians who reportedly spoke Yiddish as their first language; his father Filip and grandfather Ilie were entrepreneurs in the forestry business. Tzara's mother was Emilia Rosenstock, nee Zibalis. Owing to the Romanian Kingdom's discrimination laws, the Rosenstocks were not emancipated, and thus Tzara was not a full citizen of the country until after 1918.  He moved to Bucharest at the age of eleven, and attended the Schemitz-Tierin boarding school. It is believed that the young Tzara completed his secondary education at a state-run high school, which is identified as the Saint Sava National College or as the Sfantul Gheorghe High School. In October 1912, when Tzara was aged sixteen, he joined his friends Vinea and Marcel Janco in editing Simbolul. Reputedly, Janco and Vinea provided the funds. Like Vinea, Tzara was also close to their young colleague Jacques G. Costin, who was later his self-declared promoter and admirer.  Despite their young age, the three editors were able to attract collaborations from established Symbolist authors, active within Romania's own Symbolist movement. Alongside their close friend and mentor Adrian Maniu (an Imagist who had been Vinea's tutor), they included N. Davidescu, Alfred Hefter-Hidalgo, Emil Isac, Claudia Millian, Ion Minulescu, I. M. Rascu, Eugeniu Sperantia, Al. T. Stamatiad, Eugeniu Stefanescu-Est, Constantin T. Stoika, as well as the journalist and lawyer Poldi Chapier. In its inaugural issue, the journal even printed a poem by one of the leading figures in Romanian Symbolism, Alexandru Macedonski. Simbolul also featured illustrations by Maniu, Millian and Iosif Iser.  Although the magazine ceased print in December 1912, it played an important part in shaping Romanian literature of the period. Literary historian Paul Cernat sees Simbolul as a main stage in Romania's modernism, and credits it with having brought about the first changes from Symbolism to the radical avant-garde. Also according to Cernat, the collaboration between Samyro, Vinea and Janco was an early instance of literature becoming "an interface between arts", which had for its contemporary equivalent the collaboration between Iser and writers such as Ion Minulescu and Tudor Arghezi. Although Maniu parted with the group and sought a change in style which brought him closer to traditionalist tenets, Tzara, Janco and Vinea continued their collaboration. Between 1913 and 1915, they were frequently vacationing together, either on the Black Sea coast or at the Rosenstock family property in Garceni, Vaslui County; during this time, Vinea and Samyro wrote poems with similar themes and alluding to one another.

Answer the question at the end by quoting:

Chapter 27 is a 2007 biographical drama film depicting the murder of John Lennon by Mark David Chapman. It was written and directed by Jarrett Schaefer, based on the book Let Me Take You Down by Jack Jones, produced by Robert Salerno, and stars Jared Leto as Chapman. The film takes place in December 1980, and is intended to be an exploration of Chapman's psyche. Its title is a reference to J. D. Salinger's novel The Catcher in the Rye, which has twenty-six chapters, and suggests a continuation of the book.
The script took Schaefer four years to write, but when it was finished, the film came together quickly. With the help of producers Alexandra Milchan and Robert Salerno, Schaefer cast Jared Leto as Mark David Chapman. For his role, Leto gained 67 pounds (30 kg) by drinking microwaved pints of ice cream mixed with soy sauce and olive oil every night. Gaining the weight, he said, was tougher than dieting himself into skeletal shape for his role as drug addict Harry Goldfarb in Requiem for a Dream (2000). The abruptness of Leto's weight gain gave him gout. He had to use a wheelchair due to the stress of the sudden increase in weight put on his body.  After the shooting of the film, Leto quickly went on a liquid diet. He explained, "I've been fasting ever since. I've been doing this very strange, like, lemon and cayenne pepper and water fast. I didn't eat any food for 10 days straight; I think I lost 20 pounds that first 10 days." Losing the excess weight after Chapter 27 proved a challenge. "It took about a year to get back to a place that felt semi-normal," he said; "I don't know if I'll ever be back to the place I was physically. I'd never do it again; it definitely gave me some problems."  Twenty-two years prior to this film's production, actor Mark Lindsay Chapman, while professionally using the name Mark Lindsay, had been almost cast as John Lennon in the biopic John and Yoko: A Love Story (1985). Yoko Ono had been deeply involved in the production and had herself been initially impressed with his audition and approved his casting prior to discovering his full name was Mark Lindsay Chapman. She then nixed his casting on the grounds it was "bad karma", and a great deal of press attention was given to his having almost gotten the role. The director of Chapter 27, Jarrett Schaefer, auditioned many Lennon impersonators, but was especially impressed with Mark Lindsay Chapman's tape because he conveyed the "tough town" street-smart quality of Lennon that the impersonators failed to convey, as they always played Lennon as larger-than-life. Schaefer described Lennon as having a "chip on his shoulder and always cracking these cynical one-liners", and felt that actor Chapman was best at conveying this quality. Schaefer had some difficulty negotiating the casting with the film's producers because of Chapman's name. After Chapman was cast, he asked Chapman how he should be billed to which Chapman replied "Mark fucking Lindsay Chapman. That's my fucking name." Schaefer remarks that this was so reflective of how Lennon talked, it just reinforced his sense that Chapman was right for the part.

Who was apart of the casting for the movie?
With the help of producers Alexandra Milchan and Robert Salerno, Schaefer cast Jared Leto as Mark David Chapman.
