At the New York premiere of Hollywood film "The Great Gatsby", the noise went up for a moment and the US media was left wondering if Leonardo DiCaprio had come, but it was actually Bollywood megastar Amitabh Bachchan. The crowd's cheers were overwhelming, says Big B.

"Back from 'The Great Gatsby' premiere and has to be said... the EF (extended family) was the main attraction. Simply superb! American media, fans, security in shock. Thank you my ED, and thank you to those that cheered their lungs out. US media thought Leonardo had come, when noise went up," Big B tweeted post his "fantastic" experience.

He added had it not been for his extended family, his fans, crowding the stands, "no one would have even noticed me".

The red carpet event was "emotional" for him.


"I really have no words to express my gratitude to all of you that cheered in virtual world, and on the streets of NYC... indebted," posted the 70-year-old.

"The Great Gatsby", directed by Baz Luhrmann, marks Amitabh's Hollywood debut. He plays Meyer Wolfsheim in the $125 million 3D project, an adaptation of F. Scott Fitzgerald's novel of the same name.

The movie, which also stars Tobey Maguire and Leonardo Di Caprio, will open the 66th edition of Cannes International Film Festival, starting May 15. Amitabh will join the team on the red carpet there too.
