Background: Cristobal Perez was born on August 14, 1969 in San Antonio, Texas to Gilbert Perez, a computer programmer, and Carmen Medina. He is of Mexican-American ancestry. Perez's parents divorced in 1974, when he was four years old. His mother remarried in 1978.
Context: Roger Garcia, lead guitarist for Selena y Los Dinos, married and left the music business in 1989. The group's bassist, A.B. Quintanilla III, had heard good things about Perez from other Tejano groups. He and other band members went to watch Chris rehearse with Shelly. Quintanilla invited Chris to one of Selena's performances, and asked if he was interested in playing with Selena y Los Dinos. Chris accepted. His decision was based on Los Dinos's sound, which was more "hip and sophisticated" than other Tejano bands, and he hoped to learn more about musical arrangement from A.B., whose work he admired.  Chris auditioned for the group's manager, A.B.'s father Abraham Quintanilla, Jr. Abraham Sr. initially disliked Chris' rocker image and insisted that he change his appearance for the band. The elder Quintanilla feared that allowing Perez in the group might affect his daughter Selena's "perfect image" and ruin her career. A.B. Jr. convinced his father to accept Perez,and encouraged Chris to explore different musical genres and mold their sounds to his own tastes. He and A.B became close friends occasionally collaborated on writing songs for Selena's next recording. Chris, like Selena, knew little Spanish, and lead keyboardist Ricky Vela tutored him.  In 1991, Chris was arrested for driving under the influence and speeding in San Antonio, Texas. A police officer became involved in an altercation with his cousin, and Chris came to his cousin's aid. After the brawl, police handcuffed Chris and his cousin, but freed their friend, telling him to "run, don't walk" and to "not even turn around". When Chris was booked, police reported that they initiated a high-speed chase and were following his car. Chris Perez reported that the officers were lying, but decided not to pursue the matter because it would be "[his] word against theirs." He was released without charges, but told Selena and Abraham about his run-in with the police. They appreciated being informed and this helped gain their trust.  Several months after his arrest, he was sharing a hotel room with two road crew members of Selena y Los Dinos when the two brothers (who were intoxicated), began wrestling. Chris was also drunk and joined in the rough horseplay. One brother knocked the door off its hinges, and holes in the wall were found inside the room. Chris decided to sleep at home instead of at the hotel. Abraham Sr. fired the brothers and Chris from the band the next morning and also forbid Selena from seeing Chris.

Background: 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.
Context: The real Mark David Chapman is currently incarcerated at Wende Correctional Facility, on a guilty plea. Aside from two interviews with Larry King and Barbara Walters, both in 1992, he has not spoken with the media. However, Chapman did reveal the mechanics of his unraveling during those three days in New York City to journalist Jack Jones. The interviews were published in 1992 as Let Me Take You Down: Inside the Mind of Mark David Chapman, a book of Chapman's recollections of his act of violence. Chapter 27 is based on this text. The title "Chapter 27" suggests a continuation of J. D. Salinger's novel The Catcher in the Rye, which has twenty-six chapters, and which Chapman was carrying when he shot John Lennon. Chapman was obsessed with the book, to the point of attempting to model his life after its protagonist, Holden Caulfield.  According to the British music magazine Mojo, the title was also inspired by Chapter 27 of Robert Rosen's book Nowhere Man: The Final Days of John Lennon (2000). Rosen's book explores the numerological meaning of the number 27, "the triple 9", a number of profound importance to John Lennon. Lennon was deeply interested in numerology, particularly Cheiro's Book of Numbers, along with nine and all its multiples. It was Chapman's goal, according to Rosen, to write Chapter 27 "in Lennon's blood".  Like Chapman, Schaefer is a fan of both The Beatles and J.D. Salinger's novel The Catcher in the Rye, and said he began the script to try to understand "how someone could be inspired to kill anyone as a result of being exposed to this kind of beautiful art. It really bothered me, because Lennon and Salinger have always made me feel so much better, and so much less alone."
