Sunny Las Vegas hosted hundreds of movies or movie-scenes. Some of them got Oscar. Others got lost on way. But Vegas surely remains a classic attraction for film-makers since glory of Rat Pack days.
To be completely fair, early 60's weren't really first screen action days in Las Vegas. Frank Sinatra's first movie, Las Vegas Nights was set back in 1941. However, Rat Pack Days are always a good point to start.
The Rat Packs
Five gentlemen in Las Vegas: Sammy Davis Jr, Peter Lawford, Dean Martin, Joey Bishop and Frank Sinatra. Good friends. Loved to party. And of course, they had their own favourite place to hang out, that was Sands Hotel and Casino in Las Vegas (which was demolished in 1996, nowadays site of Venitian).
The Rat Pack Days begun in late 50's, somewhat as a reaction to Cold War early days; guys came up with ideea of having their own "summit of cool" in Las Vegas; it lasted seven years. As Sands performing scene wasn't enough for them, mighty five moved further to movies and recordings.
The seven years brought out seven films: Some Came Running, Ocean's 11, Sergents 3, 4 For Texas, Robin and 7 Hoods, Marriage on Rocks, and Cannonball Run II. Ocean's 11 (1960) is most famous one, and also benefited from a modern remake (2001), starring George Clooney, Brad Pitt and Julia Roberts. The action in new Ocean's 11 involves robbery scenes at Bellagio. The Rat Pack, released in 1998 for cable TV, includes scenes from The Sands.
The good old days gave us classic Viva Las Vegas (1964), featuring Elvis Presley, who sings his heart out for beloved "sin city".
Later, in 1970, King starred a documentary filmed at International Hotel, nowadays Las Vegas Hilton (Elvis: That's Way It Is).
The 1979 Elvis, a memorabilia to The King, stars Kurt Russell. The story goes on in 1988 with Elvis and Me, inspired by Priscilla Presley's autobiography. The 1995 BBC documentary The Burger and King: The Life and Cuisine of Elvis Presley seems to have closed Elvis & Las Vegas series, up to this moment.
