thing you need to know is that Bollywood is the name used by some
people for Bombay(Mumbai) film industry. Bombay film industry deals with
Hindi films. There are several film industries in India. All these
industries combines to make Indian Film Industry the largest in the
World. Other popular film industries in India are Tamil, Malayalam,
Telugu, Kannada, Bhojpuri etc.
There is not a fixed subject in Bollywood. There are varieties in
themes. For example the recent Oscar entry from India Taare Zameen Par
was about a 8 year old who suffers greatly until a teacher identifies
him as dyslexic. Also another Huge hit of 2008 'Rock On' is the first
Indian film to deal with the Rock Music category.
The recent trends Indicate that Bollywood is favoring stories that
seems real. This is further confirmed by the success of 'Aamir', 'A
Wednesday', 'Mumbai Meri Jaan' etc. Also the action movies had a huge
revival after the success of John Abraham starrer 'Dhoom'. Many horror
films are also in the making following the huge success of '1920',

the songs in the film. Most songs are visually rich with different
costumes & locations.
