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. CANNOTANSWER

Tropic Thunder är en svart satirisk actionkomedifilm från 2008 regisserad av Ben Stiller, som spelar huvudroller med Jack Black och Robert Downey Jr. som en grupp primadonna-skådespelare som gör en fiktiv Vietnamkrigsfilm. När deras frustrerade regissör släpper dem mitt i en djungel tvingas de förlita sig på sina skådespelarfärdigheter för att överleva den verkliga handlingen och faran. Filmmanuset av Justin Theroux, Stiller, och Etan Cohen var från en berättelse av Stiller och Theroux. Filmen producerades av Stuart Cornfeld, Stiller och Eric McLeod för Red Hour Productions och DreamWorks Pictures som en internationell samproduktion mellan USA, Tyskland, och Storbritannien. Även om södra Kalifornien och Mexiko övervägdes för huvudförbandets filminspelning valdes den hawaiiska ön Kaua'i (där Stiller har ett hem) ut för huvuddelen av skottlossningen. Kaua'i valdes framför Mexiko eftersom en skattekredit för in-statsutgifter förhandlades fram med Kaua'i Film Commission. John Toll, filmfotografen, uppgav att ön också valdes ut för sin likhet med Vietnam, baserat på dess täta lövverk, variation av terräng och väder. Kaua'i scoutades först som en möjlig plats för att filma Tropic Thunder 2004. Stiller tillbringade mer än 25 timmar under 6 veckor med att utforska ön, med hjälp av terrängfordon, båtar och helikoptrar. Efter att filmen grönbelystes av DreamWorks 2006 varade förproduktionen i sex månader, större delen av denna tid ägnades åt att spana in ytterligare platser för filminspelning. Filminspelning för Los Angeles och interiörscener förekom på uppsättningar på Universal Studios i Hollywood. Tropic Thunder var den första stora studioproduktionen på Kaua'i på fem år. Efter att filminspelningen var klar ansågs den vara den hittills största produktionen som filmats på ön, och bidrog med mer än 60 miljoner dollar till den lokala ekonomin. Tim Ryan, chefredaktör för Hawaii Film & Video Magazine, kommenterade inspelningen på ön: "Jag tror att Tropic Thunder kommer att ge Kaua'i välbehövlig och länge sysslolös publicitet på produktionsarenan ... Det borde sätta Kaua'i tillbaka på produktionsövervägande radarn." Preliminära produktionsbesättningar fanns på ön med början i december 2006 och huvudfotografering påbörjades i juli 2007, med filmning som varade i tretton veckor över sju separata platser på ön. Mycket av filmningen skedde på privat mark samt bevarandestatus utsedda områden. Casting-anrop på ön sökte 500 invånare för att porträttera byborna i filmen. Två enheter sköt samtidigt på ön från marken, och en flygenhet sköt från helikoptrar. Många av uppsättningarna och bron som användes till en av slutscenerna byggdes på tre månader. Öns oberäkneliga väder hämmade filmandet med regn- och belysningsproblem. Besättningen drabbades också av komplikationer i att flytta utrustningen och gjuta på grund av den svåra terrängen. Filmen som gav råd till bolaget Warriors Inc. värvades för att se till att krigsscenerna, inklusive den klädsel som skådespelarna bar, såg autentiska ut. Tidigare medlemmar av USA:s militär lärde skådespelarna hur de skulle hantera, avfyra och ladda om sina vapen, samt utföra olika taktiska rörelser. Den inledande krigsscenen filmades över tre veckor och krävde femtio stuntmän. Animatik användes för att kartlägga de nödvändiga kameravinklarna för filmning.
