Las Vegas is an American comedy-drama television series created by Gary Scott Thompson. It was broadcast by NBC from September 22, 2003, to February 15, 2008, airing for five seasons. It focuses on a team of people working at the Montecito, a fictional hotel and casino on the Las Vegas Strip. The employees deal with various issues that arise within the working environment, ranging from casino security to restaurant management and valet parking. Las Vegas starred James Caan, Josh Duhamel, Nikki Cox, James Lesure, Vanessa Marcil, Molly Sims, Marsha Thomason, and eventually Tom Selleck. The series originally centered on Ed Deline (Caan), a strict ex-CIA officer who serves as the president of operations for the Montecito. Former Marine Danny McCoy (Duhamel), who is Ed's protégé, later becomes the Montecito's new president.
The pilot episode began filming in March 2003, and was produced for $5 million, making it the most expensive pilot in NBC history. Production for a full season began later that year. Much of the series filming occurred at Culver Studios in California, where a set was constructed to represent the Montecito. Some filming also occasionally took place in Las Vegas. The Mandalay Bay and Green Valley Ranch, two hotel-casinos in the Las Vegas Valley, were sometimes used to portray the Montecito.
Las Vegas marked Caan's first starring role in a television series. Thomason left the series after the second season to pursue other projects, and Caan and Cox departed in 2007, after completing season four. Caan wanted to resume his acting career, and Cox was let go due to budget cuts, which were needed in order to greenlight a fifth season. After Caan's departure, Selleck was added to the cast as a new character. The series originally aired on Monday nights, before being moved to Friday nights in 2006. Ratings declined following the move, and Las Vegas was eventually canceled on February 20, 2008, ending the series with several cliffhangers.
