Background: Wladyslaw Gomulka (Polish: [vwa'diswaf go'muwka]; 6 February 1905 - 1 September 1982) was a Polish communist politician. He was the de facto leader of post-war Poland until 1948. Following the Polish October he became leader again from 1956 to 1970. Gomulka was initially very popular for his reforms; his seeking a "Polish way to socialism"; and giving rise to the period known as "Gomulka's thaw".
Context: The reformers in the Party wanted a political rehabilitation of Gomulka and his return to the Party leadership. Gomulka insisted that he be given real power to implement further reforms. He wanted a replacement of some of the Party leaders, including the pro-Soviet Minister of Defense Konstantin Rokossovsky.  The Soviet leadership viewed events in Poland with alarm. Simultaneously with Soviet troop movements deep into Poland, a high-level Soviet delegation flew to Warsaw. It was led by Nikita Khrushchev and included Mikoyan, Bulganin, Molotov, Kaganovich, Marshal Konev and others. Ochab and Gomulka made it clear that Polish forces would resist if Soviet troops advanced, but reassured the Soviets that the reforms were internal matters and that Poland had no intention of abandoning the communist bloc or its treaties with the Soviet Union. The Soviets yielded.  Following the wishes of the majority of the Politburo members, First Secretary Ochab conceded and on 20 October the Central Committee brought Gomulka and several associates into the Politburo, removed others, and elected Gomulka as first secretary of the Party. Gomulka, the former prisoner of the Stalinists, enjoyed wide popular support across the country, expressed by the participants of a massive street demonstration in Warsaw on 24 October.  A major factor that influenced Gomulka was the Oder-Neisse line issue. West Germany refused to recognize the Oder-Neisse line and Gomulka realized the fundamental instability of Poland's unilaterally imposed western border. He felt threatened by the revanchist statements put out by the Adenauer government and believed that the alliance with the Soviet Union was the only thing stopping the threat of a future German invasion. The new Party leader told the 8th Plenum of the PZPR on 19 October 1956 that: "Poland needs friendship with the Soviet Union more than the Soviet Union needs friendship with Poland... Without the Soviet Union we cannot maintain our borders with the West". Seeing that Gomulka was popular with the Polish people, and given his insistence that he wanted to maintain the alliance with the Soviet Union and the presence of the Red Army in Poland, Khrushchev decided that Gomulka was a leader that Moscow could live with. The treaty with West Germany was negotiated and signed in December 1970. The German side recognized the post-World War II borders, which established a foundation for future peace, stability and cooperation in Central Europe.  In 1967-68 Gomulka allowed outbursts of "anti-Zionist" political propaganda, which developed initially as a result of the Soviet bloc's frustration with the outcome of the Arab-Israeli Six-Day War. It turned out to be a thinly veiled anti-Semitic campaign, pursued primarily by others in the Party, but utilized by Gomulka to keep himself in power by shifting the attention of the populace from the stagnating economy and mismanagement. The result was the emigration of the majority of the remaining Polish citizens of Jewish origin. At that time he was also responsible for persecuting protesting students and toughening censorship of the media. Gomulka was one of the key leaders of the Warsaw Pact and supported Poland's participation in the intervention in Czechoslovakia in August 1968.

Background: Cameron was born in 1954 in Kapuskasing, Ontario, Canada, the son of Shirley (nee Lowe), an artist and nurse, and Phillip Cameron, an electrical engineer. His paternal great-great-great-grandfather emigrated from Balquhidder, Scotland, in 1825. Cameron grew up in Chippawa, Ontario, and attended Stamford Collegiate School in Niagara Falls, Ontario. His family moved to Brea, California in 1971, when Cameron was 17 years old.
Context: In June 2005, Cameron was announced to be working on a project tentatively titled "Project 880" (now known to be Avatar) in parallel with another project, Alita: Battle Angel (an adaptation of the manga series Battle Angel Alita). Both movies were to be shot in 3D. By December, Cameron stated that he wanted to film Battle Angel first, followed by Avatar. However, in February 2006, he switched goals for the two film projects and decided to film Avatar first. He mentioned that if both films were successful, he would be interested in seeing a trilogy being made for both. Alita: Battle Angel eventually began production in 2016 with Cameron writing and producing and Robert Rodriguez directing.  Avatar had an estimated budget of over $300 million and was released on December 18, 2009. This marked his first feature film since 1997's Titanic. It is composed almost entirely of computer-generated animation, using a more-advanced version of the "performance capture" technique used by director Robert Zemeckis in The Polar Express. James Cameron had written an 80-page scriptment for Avatar in 1995 and announced in 1996 that he would make the film after completing Titanic. In December 2006, Cameron explained that the delay in producing the film since the 1990s had been to wait until the technology necessary to create his project was advanced enough, since at the time no studio would finance for the development of the visual effects. The film was originally scheduled to be released in May 2009 but was pushed back to December 2009 to allow more time for post-production on the complex CGI and to give more time for theatres worldwide to install 3D projectors. Cameron originally intended Avatar to be 3D-only.  Avatar broke several box office records during its initial theatrical run. It grossed $749.7 million in the United States and Canada and more than $2.74 billion worldwide, becoming the highest-grossing film of all time in the United States and Canada, surpassing Cameron's Titanic. Avatar also became the first movie to ever earn more than $2 billion worldwide. Including revenue from the re-release of Avatar featuring extended footage, it grossed $760.5 million in the United States and Canada and more than $2.78 billion worldwide. It was nominated for nine Academy Awards, including Best Picture and Best Director, and won three for Best Art Direction, Best Cinematography and Best Visual Effects.  Avatar's success made Cameron the highest earner in Hollywood for 2010, netting him $257 million as reported by Vanity Fair.  Disney announced in September 2011 that it would adapt James Cameron's film Avatar into Pandora-The World of Avatar, a themed area at Disney's Animal Kingdom in Lake Buena Vista, Florida.
