Question: Dempsey was born in Lewiston, Maine, and grew up in the nearby towns of Turner and Buckfield. He has two older sisters and a half-brother, Shane. His mother, Amanda (nee Casson), was a school secretary, and his father, William, was an insurance salesman. He attended Buckfield High School and St. Dominic Regional High School.

Dempsey made a number of featured appearances in television in the 1990s; he was cast several times in pilots that were not picked up for a full season, including lead roles in the TV versions of the films The Player and About A Boy. However, he received good reviews as he portrayed real-life mob boss, Meyer Lansky in 1991 when Mobsters was put on the screen. His first major television role was a three-episode stint as Will Truman's closeted sportscaster boyfriend on Will & Grace. He went on to play the role of Aaron Brooks on Once & Again. Dempsey received an Emmy nomination in 2001 as Outstanding Guest Actor in a Drama Series for the role of Aaron. In 1993, he played a young John F. Kennedy in the two-part TV mini-series JFK: Reckless Youth. In 2000, he played Detective Kincaid in Scream 3. Dempsey had a high-profile role as the fiance of Reese Witherspoon's character in Sweet Home Alabama (2002). In 2004, he co-starred in the highly acclaimed HBO production Iron Jawed Angels, opposite Hilary Swank and Anjelica Huston. He also appeared as special guest star in The Practice for its three-episode finale season (8x13-8x15). In 2007, Dempsey starred in the Disney film Enchanted, and the Paramount Pictures film Freedom Writers, where he reunited with his Iron Jawed Angels co-star Hilary Swank. He also voiced the character Kenai in Brother Bear 2, replacing Joaquin Phoenix. Dempsey's most recent roles include the 2008 film Made of Honor as Tom, and the 2010 romantic comedy Valentine's Day; the latter film follows five interconnecting stories about Los Angelinos anticipating (or in some cases dreading) the holiday of love. Universal Pictures acquired the rights to the prize-winning novel The Art of Racing in the Rain in July 2009, for Dempsey to star in. The project has not been able to find a director. He starred as Dylan Gould in Transformers: Dark of the Moon (2011).

Problem: Gilbert and Sullivan refers to the Victorian-era theatrical partnership of the dramatist W. S. Gilbert (1836-1911) and the composer Arthur Sullivan (1842-1900) and to the works they jointly created. The two men collaborated on fourteen comic operas between 1871 and 1896, of which H.M.S. Pinafore, The Pirates of Penzance and The Mikado are among the best known. Gilbert, who wrote the libretti for these operas, created fanciful "topsy-turvy" worlds where each absurdity is taken to its logical conclusion--fairies rub elbows with British lords, flirting is a capital offence, gondoliers ascend to the monarchy, and pirates emerge as noblemen who have gone astray. Sullivan, six years Gilbert's junior, composed the music, contributing memorable melodies that could convey both humour and pathos.

Sullivan was born in London on 13 May 1842. His father was a military bandmaster, and by the time Arthur had reached the age of eight, he was proficient with all the instruments in the band. In school he began to compose anthems and songs. In 1856, he received the first Mendelssohn Scholarship and studied at the Royal Academy of Music and then at Leipzig, where he also took up conducting. His graduation piece, completed in 1861, was a suite of incidental music to Shakespeare's The Tempest. Revised and expanded, it was performed at the Crystal Palace in 1862 and was an immediate sensation. He began building a reputation as England's most promising young composer, composing a symphony, a concerto, and several overtures, among them the Overture di Ballo, in 1870. His early major works for the voice included The Masque at Kenilworth (1864); an oratorio, The Prodigal Son (1869); and a dramatic cantata, On Shore and Sea (1871). He composed a ballet, L'Ile Enchantee (1864) and incidental music for a number of Shakespeare plays. Other early pieces that were praised were his Symphony in E, Concerto for Cello and Orchestra, and Overture in C (In Memoriam) (all three of which premiered in 1866). These commissions, however, were not sufficient to keep Sullivan afloat. He worked as a church organist and composed numerous hymns, popular songs, and parlour ballads. Sullivan's first foray into comic opera was Cox and Box (1866), written with librettist F. C. Burnand for an informal gathering of friends. Public performance followed, with W. S. Gilbert (then writing dramatic criticism for the magazine Fun) saying that Sullivan's score "is, in many places, of too high a class for the grotesquely absurd plot to which it is wedded." Nonetheless, it proved highly successful, and is still regularly performed today. Sullivan and Burnand's second opera, The Contrabandista (1867) was not as successful.

What was another success of his?

The Masque at Kenilworth (1864); an oratorio, The Prodigal Son (1869); and a dramatic cantata, On Shore and Sea (1871).
