Problem: Tropic Thunder is a 2008 black satirical action comedy film directed by Ben Stiller, who stars with Jack Black and Robert Downey Jr. as a group of prima donna actors who are making a fictional Vietnam War film. When their frustrated director drops them in the middle of a jungle, they are forced to rely on their acting skills to survive the real action and danger. The screenplay by Justin Theroux, Stiller, and Etan Cohen was from a story by Stiller and Theroux. The film was produced by Stuart Cornfeld, Stiller and Eric McLeod for Red Hour Productions and DreamWorks Pictures as an international co-production between the United States, Germany, and the United Kingdom.

Although Southern California and Mexico were considered for the main unit filming, the Hawaiian island of Kaua'i (where Stiller has a home) was selected for the majority of the shooting. Kaua'i was chosen over Mexico because a tax credit for in-state spending was negotiated with the Kaua'i Film Commission. John Toll, the cinematographer, stated the island was also selected for its similarity to Vietnam, based on its dense foliage, variety of terrains, and weather. Kaua'i was first scouted as a possible location to film Tropic Thunder in 2004. Stiller spent more than 25 hours over 6 weeks exploring the island, using all-terrain vehicles, boats, and helicopters. After the film was greenlit by DreamWorks in 2006, pre-production lasted for six months, most of this time spent on scouting additional locations for filming. Filming for the Los Angeles and interior scenes occurred on sets at Universal Studios in Hollywood. Tropic Thunder was the first major studio production on Kaua'i in five years. After filming was completed, it was deemed the largest production filmed on the island to date, and contributed more than $60 million to the local economy. Tim Ryan, the executive editor of Hawaii Film & Video Magazine, commented on the filming on the island: "I think Tropic Thunder will give Kaua'i much needed and long idled publicity in the production arena ... It should put Kaua'i back on the production consideration radar." Preliminary production crews were on the island starting in December 2006 and principal photography began in July 2007, with filming lasting thirteen weeks over seven separate locations on the island. Much of the filming took place on private land as well as conservation status designated areas. Casting calls on the island sought 500 residents to portray the villagers in the film. Two units shot simultaneously on the island from the ground, and an aerial unit shot from helicopters. Many of the sets and the bridge used for one of the final scenes were built in three months. The island's erratic weather hampered filming with rain and lighting issues. The crew also faced complications in moving the equipment and cast due to the difficult terrain. The film advising company Warriors Inc. was enlisted to ensure the war scenes, including the attire worn by the actors, looked authentic. Former members of the U.S. military taught the actors how to handle, fire, and reload their weapons, as well as perform various tactical movements. The opening war scene was filmed over three weeks and required fifty stuntmen. Animatics were used to map out the necessary camera angles for filming.

Problem: Jacob Gedleyihlekisa Zuma (Zulu: [gelZhejile'kisa 'zhuma]; born 12 April 1942) is a South African politician who served as the fourth President of South Africa from the 2009 general election until his resignation on 14 February 2018. Zuma is also referred to by his initials JZ and his clan name Msholozi. Zuma served as Deputy President of South Africa from 1999 to 2005, but was dismissed by President Thabo Mbeki in 2005 after Zuma's financial adviser, Schabir Shaik, was convicted of soliciting a bribe for Zuma. Zuma was nonetheless elected President of the African National Congress (ANC) on 18 December 2007 after defeating Mbeki at the ANC conference in Polokwane.

While serving as deputy president, Zuma enjoyed considerable support in parts of the left wing of the ANC, including many in the ANC Youth League, the South African Communist Party and the Congress of South African Trade Unions (COSATU). While Zuma faced corruption charges, these organisations remained supportive of him. Zuma's dismissal was interpreted in two ways. Many international observers hailed it as a clear sign that the South African government was dedicated to rooting out corruption within its own ranks. On the other hand, some within South Africa focused on the fact that Zuma and Mbeki represent different constituencies within the African National Congress. Some left-wing supporters claimed that Mbeki and his more market-oriented wing of the party had conspired to oust Zuma to entrench their dominance in the ANC. Zuma's cause rallied large crowds of supporters at each of his corruption-related court appearances in 2005. At one court date, Zuma supporters burned T-shirts with Mbeki's picture on them, which earned the condemnation of the ANC; Zuma and his allies urged a return to party discipline for subsequent gatherings. At the next court date in November, Zuma supporters numbering in the thousands gathered to support him; he addressed the Durban crowd in Zulu, urging party unity and singing the apartheid-era struggle song Lethu Mshini Wami with lyrics that translate literally as "bring me my machine" but understood to refer to a machine gun. At an October tour for the ANC Youth League elsewhere in the country, Zuma also earned the cheers of large crowds. While his political strength was at least partly based on his relationships within intra-party politics, one analyst argued that his supporters' loyalty could be explained as rooted in a Zulu approach to loyalty and mutual aid. Because of his support among elements of the party, Zuma remained a powerful political figure, retaining a high position in the ANC even after his dismissal as the country's deputy president. A panel of political analysts convened in November 2005 agreed that if he was to be found innocent of the corruption charges brought against him, it would be hard for any other potential ANC candidate to beat Zuma in the race for the country's presidency in 2009. However, these analysts also questioned whether Zuma was indeed a left-wing candidate of the sort that many of his supporters seem to seek, and noted that the global and national economic constraints that have shaped Mbeki's presidency would be no different in the next presidential term.
