"Shall reveal name of the '3 mistakes' movie soon. Hint: it's a Gujarati name," tweeted Bhagat.
The author is impressed with the movie's first look.
"Saw first look posters for the '3 mistakes' movie. Wow! You shall be proud. But @utvfilms won't let me share them yet. Soon I promise," he added.
So far, two of Bhagat's books -- "Five Point Someone" and "One Night @ the Call Center", have inspired films - "3 Idiots" and "Hello" respectively.
"Hello" was released in 2008 but was not such a big success. But "3 Idiots", which talks about the life of three engineering students, went on to become the biggest hit of 2009.
The rights of his last novel "Revolution 2020" have been bagged by UTV Motion Pictures.
