Well, not an Indian but she can be labelled as a Kollywood actress for her performance in "Madrasapattinam". Yes, that's Amy Jackson for you. I got a chance to see this movie recently, and her acting is definitely commendable.
Here's an article in a British Daily "METRO" on August 17th, 2010 publication. The newspaper has categorised Amy as a Bollywood entrant which is technically not right, but outside India, all Indian movies apparently fall under Bollywood. So all you Kollywood fanatics, please pardon this daily and enjoy this read.
