Some Bollywood films are inspired by Hollywood tales, but most are original ideas,
often based on moral or family dilemmas. Like Hollywood, the star system is an important
part of Bollywood and the biggest actors and actresses are celebrities in their own right.
Unlike Hollywood, however, Indian actors often work on several films at one time, even
switching between movie sets in the same day. And while Hollywood left behind its musicals
in the 1950s, Bollywood films always contain a performance element. Actors have to
demonstrate impeccable dancing skills as well as acting ability.
