Philip Henry Sheridan (March 6, 1831 - August 5, 1888) was a career United States Army officer and a Union general in the American Civil War. His career was noted for his rapid rise to major general and his close association with General-in-chief Ulysses S. Grant, who transferred Sheridan from command of an infantry division in the Western Theater to lead the Cavalry Corps of the Army of the Potomac in the East. In 1864, he defeated Confederate forces in the Shenandoah Valley and his destruction of the economic infrastructure of the Valley, called "The Burning" by residents, was one of the first uses of scorched earth tactics in the war. In 1865, his cavalry pursued Gen. Robert E. Lee and was instrumental in forcing his surrender at Appomattox.
The protection of the Great Plains fell under the Department of the Missouri, an administrative area of over 1,000,000 mi.2, encompassing all land between the Mississippi River and the Rocky Mountains. Maj. Gen. Winfield Scott Hancock was assigned to the department in 1866 but had mishandled his campaign, resulting in Sioux and Cheyenne raids that attacked mail coaches, burned the stations, and killed the employees. They also killed and kidnapped a considerable number of settlers on the frontier. Under pressure from the governors, General Grant turned to Sheridan. In September 1866, Sheridan arrived at the former Fort Martin Scott near Fredericksburg, Texas, where he spent three months subduing Indians in the Texas Hill Country.  In August 1867, Grant appointed Sheridan to head the Department of the Missouri and pacify the Plains. His troops, even supplemented with state militia, were spread too thin to have any real effect. He conceived a strategy similar to the one he used in the Shenandoah Valley. In the Winter Campaign of 1868-69 (of which the Battle of Washita River was part) he attacked the Cheyenne, Kiowa, and Comanche tribes in their winter quarters, taking their supplies and livestock and killing those who resisted, driving the rest back into their reservations. When Sherman was promoted to General of the Army following Grant's election as President of the United States, Sheridan was appointed to command the Military Division of the Missouri, with all the Great Plains under his command. Professional hunters, trespassing on Indian land, killed over 4 million bison by 1874, and Sheridan applauded: "Let them kill, skin and sell until the buffalo is exterminated". When the Texas legislature considered outlawing bison poaching on tribal lands, Sheridan personally testified against it, suggesting that the legislature should give each of the hunters a medal, engraved with a dead buffalo on one side and a discouraged-looking Indian on the other.  Eventually the Indians returned to their designated reservations. Sheridan's department conducted the Red River War, the Ute War, and the Great Sioux War of 1876-77, which resulted in the death of a trusted subordinate, Lt. Col. George Armstrong Custer. The Indian raids subsided during the 1870s and were almost over by the early 1880s, as Sheridan became the commanding general of the U.S. Army.  Comanche Chief Tosawi reputedly told Sheridan in 1869, "Tosawi, good Indian," to which Sheridan supposedly replied, "The only good Indians I ever saw were dead." In Bury My Heart at Wounded Knee, Dee Brown attributed the quote to Sheridan, stating that "Lieutenant Charles Nordstrom, who was present, remembered the words and passed them on, until in time they were honed into an American aphorism: The only good Indian is a dead Indian. Sheridan denied he had ever made the statement. Biographer Roy Morris Jr. states that, nevertheless, popular history credits Sheridan with saying "The only good Indian is a dead Indian." This variation "has been used by friends and enemies ever since to characterize and castigate his Indian-fighting career."

Joaquin Rafael Phoenix (; ne Bottom; born October 28, 1974) is an American actor, producer, and activist. For his work as an actor, Phoenix has received a Grammy Award, a Golden Globe Award, and has three Academy Award and British Academy Film Award nominations. Phoenix started acting in television shows with his brother River Phoenix and sister Summer Phoenix.
In 2006, Phoenix was invited to join the Academy of Motion Picture Arts and Sciences.  In 2007, Phoenix reunited with director James Gray for the film We Own the Night, which he also produced. In the film, Phoenix played a New York nightclub manager who tries to save his brother and father from Russian mafia hit men. The film premiered at the 2007 Cannes Film Festival, receiving mixed reviews from critics and grossed a total of $54.5 million worldwide. Critic Peter Travers described Phoenix as "electrifying and then some", and he was awarded the People's Choice Award for Favorite Leading Man for the performance. For his second film of 2007, Phoenix also reunited with director Terry George for the film Reservation Road. In it, Phoenix played a father obsessed with finding out who killed his son in a hit-and-run accident. The film failed at the box office  and received negative reviews from critics, with film critic Peter Travers writing "Even the best actors -- and I'd rank Joaquin Phoenix and Mark Ruffalo among their generation's finest -- can't save a movie that aims for tragedy but stalls at soap opera."  Phoenix made his third collaboration with director James Gray in the film Two Lovers (2008), where he played a bachelor torn between the family friend his parents wish he would marry and his beautiful but volatile new neighbor. Two Lovers premiered in competition at the 2008 Cannes Film Festival in May, receiving largely positive reviews, especially Phoenix who was praised by film critics David Edelstein who wrote "He [Phoenix] is, once again, stupendous, and stupendous in a way he has never been before" and Roger Ebert describing his performance as "perfect pitch". Two Lovers grossed $16 million worldwide.  Phoenix's mockumentary film I'm Still Here (2010) premiered at the 67th Venice International Film Festival on September 6, 2010. The film was directed by Phoenix's then brother-in-law Casey Affleck and was also written by Affleck and Phoenix himself. The film purports to follow the life of Phoenix, from the announcement of his retirement from acting, through his transition into a career as a hip hop artist. Filming officially began on January 16, 2009 at a Las Vegas nightclub. Throughout the filming period, Phoenix remained in character for public appearances, giving many the impression that he was genuinely pursuing a new career. Although widely suspected to be a "mockumentary," the fact that the events of the film had been deliberately staged was not disclosed until after the film had been released. The film received mixed reviews and failed at the box office. After the releasing of the film, Phoenix took a self-imposed break from acting.

What did he first produce?
In 2007, Phoenix reunited with director James Gray for the film We Own the Night, which he also produced.
