When Anurag Kashyap's That Girl With Yellow Boots showed at TIFF2010, someone asked him in the Q&A that was held afterwards if he'd ever thought about making a mainstream Bollywood film -- Kashyap's response was something along the lines that if he tried, it would be something totally crazy.
After watching this long anticipated trailer, I think we have the answer to a related question: if Kashyap produced a Bollywood film, what would it look like? Director Sachin Kunkalkar's Aiyyaa:
I want to see this film so badly I could almost cry. Lucky, lucky London folks who will get to see this at the BFI London Film Festival. I would pretty much place money on the fact that we're not likely to see this in cinemas here.
