Summarize this article in one sentence.
To get a feel of the type of roles, current acting style and dialog delivery of the well-known actors and actresses, it is very important to watch Hindi movies. Immerse yourself in them. Develop a refined appreciation for them to the point where you can't see yourself doing anything else. Make them a part of your life.  There are sources to watch Hindi movies online, like FridayMasti.com that can help widen your Bollywood horizons.  This will help you understand the culture, too. Read about the area and keep up with news and trends to supplement your knowledge as well. In order for casting agents to take you seriously, you've got to have a portfolio. Have professional photographs taken and make an audition tape or DVD that shows your acting, singing and dancing skills. It should also show snippets of the work you've already done. Promote yourself on sites like YouTube, where you can develop your own following independently. If you have your own professional website, even better. This could be an extra or walk-on role in a film or a stunt double. Accept parts in commercials, on television shows, reality and game shows. Try to get work as a model, too. You can't start at the top – you've got to work your way up. It's all a step in the right direction. Film studios are centered around Mumbai's Juhu district. Film scouts looking for extras and tourists are usually most active in the early morning hours. It takes just as much charisma, talent and ability to be "discovered" in Bollywood as it does in Hollywood. Competition is high and connections are important. Further, it's difficult to work in Bollywood if you are not of Indian descent. Determine whether you actually have a chance to make it before committing a lot of time and energy to learn how to become a Bollywood actress. While you're working your way up, you'll need a source of income. Many of those aiming for stardom having something else they do on the side until they get their big break. It's good to have a fall back in the case that it doesn't work out.

Summary:
Watch (and love) Hindi movies. Build a portfolio. Look for minor roles to get started. Be honest with yourself about your star quality.
