IN: 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.
QUESTION: Who acted in chapter 27?
IN: Delgado was born in Aguadilla, Puerto Rico to Carlos "Cao" Delgado and Carmen Digna Hernandez. He grew up in the El Prado section of Aguadilla. There, he attended elementary school alongside his three siblings. Both his father, "Don Cao", and his grandfather, Asdrubal "Pingolo" Delgado, were well-known figures in the town.

Like his hero, Delgado is a well-known peace activist, and has been open about his political beliefs. As part of the Navy-Vieques protests, Delgado was actively opposed to the use of the island of Vieques, Puerto Rico as a bombing target practice facility by the United States Department of Defense, until bombing was halted in 2003. He is also against the occupation of Iraq. In the 2004 season, Delgado protested the war by silently staying in the dugout during the playing of "God Bless America" during the seventh inning stretch. Delgado does not make a public show of his beliefs, and even his teammates were not aware of his views until a story was published in July 2004 in the Toronto Star. Delgado was quoted as saying "It's a very terrible thing that happened on September 11. It's (also) a terrible thing that happened in Afghanistan and Iraq, ... I just feel so sad for the families that lost relatives and loved ones in the war. But I think it's the stupidest war ever." The story was the subject of a media frenzy, mostly in New York, where on July 21, 2004, as was anticipated, Delgado was booed by Yankee fans for his passive protest during a game at Yankee Stadium. Delgado had explained that the playing of "God Bless America" had come to be equated with a war in which he didn't believe. In a New York Times interview, Delgado said this is what he believed in, and "It takes a man to stand up for what he believes." After being traded to the Mets, in a conciliatory measure, Delgado opted to stand during the singing of "God Bless America."  Among other charity work, Delgado is well known for his generous visits to hospitals in his hometown where, on Three Kings Day, he brings toys to hospitalized children. In 2006, he joined Puerto Rico's Senate President in co-sponsoring a massive Three Kings gift-giving effort in the town of Loiza. Delgado started his own non-profit organization, "Extra Bases" to assist island youth. In 2007, Delgado donated video conference equipment to allow his hometown's Buen Samaritano Hospital to establish a regular link with a hospital in Boston in order to allow for remote diagnoses through telemedicine.  Delgado has also contributed to improving Puerto Rico's public education system. In 2007, he participated in "Sapientis Week", an initiative sponsored by the non-profit Sapientis which brings distinguished public figures into classrooms in order to raise the public's awareness of the education crisis in Puerto Rico. Delgado taught a class on Athletic Mental Training and Health at the Ramon Power y Giralt School in the Luis Llorens Torres public housing complex.  For his efforts, Delgado was awarded the Roberto Clemente Award in 2006. The award goes to the player in baseball who best exemplifies humanitarianism and sportsmanship, and was named after Hall of Famer Roberto Clemente in 1973. Prior to the 2008 season of the Puerto Rico Baseball League, Delgado was involved in an initiative to provide economic help to the Indios de Mayaguez team.
