Oklahoma! is the first musical written by the team of composer Richard Rodgers and librettist Oscar Hammerstein II. The musical is based on Lynn Riggs' 1931 play, Green Grow the Lilacs. Set in Oklahoma Territory outside the town of Claremore in 1906, it tells the story of cowboy Curly McLain and his romance with farm girl Laurey Williams. A secondary romance concerns cowboy Will Parker and his flirtatious fiancée, Ado Annie.

The original Broadway production opened on March 31, 1943. It was a box-office smash and ran for an unprecedented 2,243 performances, later enjoying award-winning revivals, national tours, foreign productions and an Academy Award-winning 1955 film adaptation. It has long been a popular choice for school and community productions.

This musical, building on the innovations of the earlier Show Boat, epitomized the development of the "book musical", a musical play where the songs and dances are fully integrated into a well-made story with serious dramatic goals that are able to evoke genuine emotions other than laughter. In addition, Oklahoma! features musical themes, or motifs, that recur throughout the work to connect the music and story.^{[page needed]} A fifteen-minute "dream ballet" reflected Laurey's struggle to choose between two men. A special Pulitzer Prize was awarded to Richard Rodgers and Oscar Hammerstein II for Oklahoma! in the category of "Special Awards And Citations – Letters" in 1944.

Oklahoma (ⁱ/ˌoʊkləˈhoʊmə/) (Pawnee: Uukuhuúwa , Cayuga: Gahnawiyoˀgeh ) is a state located in the South Central region of the United States of America. Oklahoma is the 20th most extensive and the 28th most populous of the 50 United States. The state's name is derived from the Choctaw words okla and humma, meaning "red people", and it is known informally by its nickname, The Sooner State. Formed by the combination of Oklahoma Territory and Indian Territory on November 16, 1907, Oklahoma was the 46th state to enter the union. Its residents are known as Oklahomans or, informally "Okies", and its capital and largest city is Oklahoma City.

A major producer of natural gas, oil, and agriculture, Oklahoma relies on an economic base of aviation, energy, telecommunications, and biotechnology. It has one of the fastest growing economies in the nation, ranking among the top states in per capita income growth and gross domestic product growth. Oklahoma City and Tulsa serve as Oklahoma's primary economic anchors, with nearly 60 percent of Oklahomans living in their metropolitan statistical areas.

Hugh Michael Jackman (born 12 October 1968) is an Australian actor and producer who is involved in film, musical theatre, and television.

Jackman has won international recognition for his roles in major films, notably as action/superhero, period and romance characters. He is known for his role as Wolverine in the X-Men film series, as well as for his leads in Kate & Leopold, Van Helsing, The Prestige, Australia, and Real Steel. Jackman is a singer, dancer, and actor in stage musicals, and won a Tony Award for his role in The Boy from Oz.

In November 2008, Open Salon named Jackman one of the sexiest men alive. Later that same month, People magazine named Jackman "Sexiest Man Alive."

A three-time host of the Tony Awards, winning an Emmy Award for one of these appearances, Jackman also hosted the 81st Academy Awards on 22 February 2009.

Jackman was born in Sydney, New South Wales, the youngest of five children of English parents Chris Jackman and Grace Watson, and the second child to be born in Australia (he also has a younger half-sister, from his mother's re-marriage). One of his paternal great-grandfathers was Greek. His parents divorced when he was eight, and he remained with his accountant father and siblings, while his mother moved back to England. As a child, Jackman liked the outdoors, spending a lot of time at the beach and on camping trips and vacations all over Australia. He wanted to see the world: "I used to spend nights looking at atlases. I decided I wanted to be a chef on a plane. Because I'd been on a plane and there was food on board, I presumed there was a chef. I thought that would be an ideal job."
