Question: 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.

Problem: Vaslav Nijinsky (also Vatslav; Russian: Vatslav Fomich Nizhinskii; Russian: ['vatsl@f f@'mjitc njI'zinskjIj]; Polish: Waclaw Nizynski; 12 March 1889/1890 - 8 April 1950) was a ballet dancer and choreographer cited as the greatest male dancer of the early 20th century.

Vaslav Nijinsky was born in 1889 or 1890 in Kiev, Russian Empire (now Ukraine), as Waclaw Nizynski, to ethnic Polish parents, touring dancers Tomasz Nizynski (b. 7 March 1862) and Eleonora Bereda (b. 28 December 1856). Nijinsky was christened in Warsaw. He identified himself as Polish although he grew up in the interior of Russia with his parents and he had difficulty speaking Polish.  Eleanora, along with her two brothers and two sisters, was orphaned while still a child. She started to earn a living as an extra in Warsaw's Grand Theatre Ballet (Polish: Teatr Wielki), becoming a full member of the company at age thirteen. In 1868 her talent was spotted and she moved to Kiev as a solo dancer. Tomasz Nizynski also attended the Wielki Theatre school, becoming a soloist there. At age 18 he accepted a soloist contract with the Odessa Theatre. The two met, married in May 1884 and settled into a career with the traveling Setov opera company. Tomasz was premier danseur, and Eleanora a soloist. Eleanora continued to tour and dance while having three children, sons Stanislav Fomitch (b. 29 December 1886 in Tiflis) and Vaslav; and daughter Bronislava Fominitchna ('Bronia', b. 8 January 1891 in Minsk). She suffered from depression, which may have been a genetic vulnerability shared in a different form by her son Vaslav. Both boys received training from their father and appeared in an amateur Hopak production in Odessa in 1894.  After Josef Setov died about 1894, the company disbanded. Thomas attempted to run his own company, but was not successful. He and his family became itinerant dancers, the children appearing in the Christmas show at Nizhny Novgorod. In 1897 Thomas and Eleanora separated after Thomas had fallen in love with another dancer, Rumiantseva, while touring in Finland. Eleanora moved to 20 Mokhovaya Street in St Petersburg with her children. She persuaded a friend from the Wielki Theatre, Victor Stanislas Gillert, who was at the time teaching at the Imperial Ballet School, to help get Vaslav into the school. He arranged for the noted teacher Enrico Cecchetti to sponsor the application. Bronia entered the school two years after Vaslav. Their older brother Stanislav had suffered a fall from a window when young and seemed to have suffered some brain damage. Vaslav and Bronia, just two years apart, became very close as they grew. As he got older, Stanislav became increasingly mentally unstable and would have fierce tantrums. He was admitted to an asylum for the insane in 1902.

At what point did he become interested in ballet?
