Hindi-Urdu and Bollywood
The predominant Indian film industry Bollywood, located in Mumbai, Maharashtra uses dialects of Hindi-Urdu, Awadhi, Rajasthani, Bhojpuri, Punjabi and Bambaiya Hindi, along with liberal use of English for the dialogue and soundtrack lyrics.
Movie titles are often screened in three scripts: Latin, Devanagari and Perso-Arabic. The use of Urdu or Hindi in films depends on the film's context: historical films set in the Delhi Sultanate or Mughal Empire are almost entirely in Urdu, while films based on Hindu mythology make heavy use of Hindi with Sanskrit vocabulary.
