"The last one week has been very busy with '3 Idiots' work. The final song is done and now the cut is locked too. I think we have managed to make the film that we set out to. In the coming weeks I will tell you more about the film and what is happening," Aamir posted on his blog.

"As you can well imagine the good old butterflies have begun to spread their wings once again and their feathery touch has started to tickle my insides. I'm tempted to try and snuff them out with smoke...but I won't. I think this time I have quit for good," he said.
