Question:
Rockefeller was the second of six children and eldest son born in Richford, New York to con artist William Avery "Bill" Rockefeller (November 13, 1810 - May 11, 1906) and Eliza Davison (September 12, 1813 - March 28, 1889). His siblings were Lucy (1838-1878), William Jr. (1841-1922), Mary (1843-1925) and twins Franklin (Frank) (1845-1917) and Frances (1845-1847). His father was of English and German descent while his mother was of Scots-Irish descent. Bill was first a lumberman and then a traveling salesman who identified himself as a "botanic physician" and sold elixirs.
In 1859, Rockefeller went into the produce commission business with a partner, Maurice B. Clark, and they raised $4,000 ($108,948 in 2017 dollars) in capital. Rockefeller went steadily ahead in business from there, making money each year of his career. While his brother Frank fought in the Civil War, Rockefeller tended his business and hired substitute soldiers. He gave money to the Union cause, as did many rich Northerners who avoided combat. Rockefeller was an abolitionist who voted for President Abraham Lincoln and supported the then-new Republican Party. As he said, "God gave me money", and he did not apologize for it. He felt at ease and righteous following Methodist preacher John Wesley's dictum, "gain all you can, save all you can, and give all you can." At that time, the Federal government was subsidizing oil prices, driving the price up from $.35 a barrel in 1862 to as high as $13.75. This created an oil-drilling glut, with thousands of speculators attempting to make their fortunes. Most failed, but those who struck oil did not even need to be efficient. They would blow holes in the ground and gather up the oil as they could, often leading to creeks and rivers flowing with wasted oil in the place of water. In this environment of wasteful boom, the partners switched from foodstuffs to oil, building an oil refinery in 1863 in "The Flats", then Cleveland's burgeoning industrial area. The refinery was directly owned by Andrews, Clark & Company, which was composed of Clark & Rockefeller, chemist Samuel Andrews, and M. B. Clark's two brothers. The commercial oil business was then in its infancy. Whale oil had become too expensive for the masses, and a cheaper, general-purpose lighting fuel was needed. While other refineries would keep the 60% of oil product that became kerosene, but dump the other 40% in rivers and massive sludge piles, Rockefeller remained as thrifty and efficient as ever, using the gasoline to fuel the refinery, and selling the rest as lubricating oil, petroleum jelly and paraffin wax, and other by-products. Tar was used for paving, naphtha shipped to gas plants. Likewise, Rockefeller's refineries hired their own plumbers, cutting the cost of pipe-laying in half. Barrels that cost $2.50 each ended up only $.96 when Rockefeller bought the wood and had them built for himself. In February 1865, in what was later described by oil industry historian Daniel Yergin as a "critical" action, Rockefeller bought out the Clark brothers for $72,500 (equivalent to $1 million in 2017 dollars) at auction and established the firm of Rockefeller & Andrews. Rockefeller said, "It was the day that determined my career." He was well positioned to take advantage of postwar prosperity and the great expansion westward fostered by the growth of railroads and an oil-fueled economy. He borrowed heavily, reinvested profits, adapted rapidly to changing markets, and fielded observers to track the quickly expanding industry.

Question:
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.
