The 'musical' film is a film genre where several songs are sung by the characters in the film. The songs usually tell a story or develop the film's characters.
Musicals developed after the silent film genre. The Warner Brothers studio produced the ' Jazz Singer' in 1927, starring Al Jolson singing. This film encouraged Hollywood to develop more sound pictures.
Musical film stars include, Fred Astaire, Ginger Rogers and Elvis Presley to Madonna (in ' Evita') and Nicole Kidman (in ' Moulin Rouge').
The genre has further developed and extended to include the new genre called ‘Bollywood’. These are Indian Musical films such as ' The Guru'.
