Well, one thing that does not differ between Bollywood and Hollywood is the sequel principle. Don madke a ton of rupees, so Akhtar, Khan, Chopra, and special surprise guest star Hrithik Roshan are back on the chase to catch Don. Shah Rukh Khan went directly from completing his sci-fi/superhero epic Ra.One in London and Mumbai to shooting Don 2 in Berlin. At this point there isn't much beyond paparazzi photos of the set to speak of, but there have already been reports of some serious car chase action and near misses, with Khan driving into a very expensive camera in one stunt shot gone wrong.
Bollywood does not mess around when it comes to scope, I'll tell you that much. So I would expect some very scenic destruction. I really enjoyed the first Don and I recommend it highly to anyone looking for an entry point into modern Indian action films.
Don 2 is due before the end of 2011.
