Background: Cooper was born on May 7, 1901, in Helena, Montana to Alice (nee Brazier, 1873-1967) and Charles Henry Cooper (1865-1946). His father had emigrated from Houghton Regis, Bedfordshire and was a prominent lawyer, rancher, and (later) a Montana Supreme Court justice. His mother had emigrated from Gillingham, Kent and married Charles in Montana. In 1906, Charles purchased the 600-acre (240 ha) Seven-Bar-Nine cattle ranch about fifty miles (eighty kilometers) north of Helena near the town of Craig on the Missouri River.
Context: For me the really satisfying things I do are offered me, free, for nothing. Ever go out in the fall and do a little hunting? See the frost on the grass and the leaves turning? Spend a day in the hills alone, or with good companions? Watch a sunset and a moonrise? Notice a bird in the wind? A stream in the woods, a storm at sea, cross the country by train, and catch a glimpse of something beautiful in the desert, or the farmlands? Free to everybody ... Cooper's twenty-year friendship with Ernest Hemingway began at Sun Valley in October 1940. The previous year, Hemingway drew upon Cooper's image when he created the character of Robert Jordan for the novel For Whom the Bell Tolls. The two shared a passion for the outdoors, and for years they hunted duck and pheasant, and skied together in Sun Valley. Both men admired the work of Rudyard Kipling--Cooper kept a copy of the poem "If--" in his dressing room--and retained as adults Kipling's sense of boyish adventure. As well as admiring Cooper's hunting skills and knowledge of the outdoors, Hemingway believed his character matched his screen persona, once telling a friend, "If you made up a character like Coop, nobody would believe it. He's just too good to be true." They saw each other often, and their friendship remained strong through the years. Cooper's social life generally centered on sports, outdoor activities, and dinner parties with his family and friends from the film industry, including directors Henry Hathaway, Howard Hawks, William Wellman, and Fred Zinnemann, and actors Joel McCrea, James Stewart, Barbara Stanwyck, and Robert Taylor. As well as hunting, Cooper enjoyed riding, fishing, skiing, and later in life, scuba diving. He never abandoned his early love for art and drawing, and over the years, he and his wife acquired a private collection of modern paintings, including works by Pierre-Auguste Renoir, Paul Gauguin, and Georgia O'Keeffe. Cooper owned several works by Pablo Picasso, whom he met in 1956. Cooper also had a lifelong passion for automobiles, with a collection that included a 1930 Duesenberg. Cooper was naturally reserved and introspective, and loved the solitude of outdoor activities. Not unlike his screen persona, his communication style frequently consisted of long silences with an occasional "yup" and "shucks". He once said, "If others have more interesting things to say than I have, I keep quiet." According to his friends, Cooper could also be an articulate, well-informed conversationalist on topics ranging from horses, guns, and Western history to film production, sports cars, and modern art. He was modest and unpretentious, frequently downplaying his acting abilities and career accomplishments. His friends and colleagues described him as charming, well-mannered, and thoughtful, with a lively boyish sense of humor. Cooper maintained a sense of propriety throughout his career and never misused his movie star status--never sought special treatment or refused to work with a director or leading lady. His close friend Joel McCrea recalled, "Coop never fought, he never got mad, he never told anybody off that I know of; everybody that worked with him liked him."

Background: Rogen was born in Vancouver, British Columbia. His mother, Sandy (nee Belogus), is a social worker, and his father, Mark Rogen, worked for non-profit organizations and as an assistant director of the Workmen's Circle Jewish fraternal organization. Since Rogen's father is American, he has American citizenship by birth, though the actor has stated "I definitely associate with being Canadian much more than being American" because he grew up in Canada. He has described his parents, who met on kibbutz Beit Alfa in Israel, as "radical Jewish socialists".
Context: Rogen began dating writer/actress Lauren Miller in 2004. The two met while he was working on Da Ali G Show. The couple became engaged on September 29, 2010, and married on October 2, 2011 in Sonoma County, California, where they continue to reside. Miller has had minor on-screen roles in a few of Rogen's films. Rogen has been outspoken about awareness of Alzheimer's disease. No one in his biological family has it but it runs in his wife's side, and has affected her mother for several years. "I think until you see it firsthand, it's kind of hard to conceive of how brutal it is," Rogen said to CNN. "Until I saw it, you just don't get kind of how heartbreaking it can be." During the interview, he talked about how he tries to be emotionally supportive and around as much as he can for Miller's mother. Both he and Miller spoke to Larry King for A Larry King Special, Unthinkable: The Alzheimer's Epidemic, which aired in April 2011. Rogen testified about the disease and his charity before the United States Senate Appropriations Subcommittee on Labor, Health and Human Services on February 26, 2014. Rogen started the Hilarity for Charity movement, to inspire change and raise awareness of Alzheimer's disease among the Millennial Generation. On February 25, 2016, Rogen and Miller were honored with the unite2gether accolade from unite4:humanity for their work promoting awareness and raising money for Alzheimer's research through Hilarity for Charity. Rogen appeared in a Bud Light commercial celebrating LGBT Pride Month and the Supreme Court of the United States ruling same-sex couples the right to marry. He is a purported muse for the gay community, calling himself a "Bear Icon" in an appearance on Conan.
