Question: 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.

Question: 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.

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.
