Question: Alfred Cellier (1 December 1844 - 28 December 1891) was an English composer, orchestrator and conductor. In addition to conducting and music directing the original productions of several of the most famous Gilbert and Sullivan works and writing the overtures to some of them, Cellier conducted at many theatres in London, New York and on tour in Britain, America and Australia. He composed over a dozen operas and other works for the theatre, as well as for orchestra, but his 1886 comic opera, Dorothy, was by far his most successful work. It became the longest-running piece of musical theatre in the nineteenth century.

In December 1877 Cellier joined the D'Oyly Carte company as musical director at the Opera Comique in London. There he conducted The Sorcerer (1877), H.M.S. Pinafore (1878, for which he wrote the overture, based on themes from the opera), Trial by Jury (1878), George Grossmith's Cups and Saucers (1878-79), and three of his own one-act works: Dora's Dream (1877-78 revival), The Spectre Knight (1878), and After All! (1878-79). Cellier was conducting the performance of Pinafore during which the partners of The Comedy Opera Company attempted to repossess the set, and he was noted for his attempts to calm the audience during the fracas. His brother, Francois, succeeded him as musical director at the Opera Comique in 1879. Alfred Cellier was a conductor of a series of promenade concerts at the Queen's Theatre, Long Acre and, in 1878-1879 he was joint conductor, with Sullivan, of the Covent Garden Promenade Concerts.  In 1879, he travelled with Gilbert, Sullivan, and Carte to America, where he acted as conductor for Pinafore and The Pirates of Penzance, with Carte's first American touring company. Cellier prepared the overture to Pirates using Sullivan's music from the rest of the score. Back in London in July 1880, he directed the music at the Opera Comique for Pirates and another of his own pieces with Desprez, In the Sulks. In April 1881, he left the D'Oyly Carte company, ceding the baton to his brother. Cellier composed a three-act grand opera, Pandora, a version of Longfellow's The Masque of Pandora (with a libretto by B. C. Stephenson) that was presented in Boston in 1881. He returned to America later that year as music director of D'Oyly Carte's New York and touring productions of Billee Taylor (1882), Les Manteaux Noirs and Rip Van Winkle (both in the fall of 1882), and Iolanthe (1882-83), for the latter of which he prepared the New York overture.  In 1883, Cellier's setting of Gray's Elegy, in the form of a cantata, was produced at the Leeds music festival. In 1883, Cellier left the D'Oyly Carte company, but he was back for brief periods as music director with D'Oyly Carte's touring companies for Princess Ida (1884) and The Mikado (1885). In 1885, also, Cellier composed incidental music for a production of As You Like It. He composed two more companion pieces that had Savoy Theatre premieres: The Carp (performed with The Mikado and Ruddigore in 1886-87), and Mrs. Jarramie's Genie (composed together with his brother Francois, with libretti by Desprez, which played together with several different operas at the Savoy between 1887 and 1889).  While in London, Cellier conducted at several London theatres, including the Criterion, the St James's, and the Savoy. Later, as a result of ill health, he resided abroad, notably in America and Australia, where he was a representative for the D'Oyly Carte company.

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.
