Bollywood actor Amitabh Bachchan is angry over "rubbish" and "malicious" comments being posted on a fake Twitter account that bears his name. The account has been used to post less than complimentary comments about fellow actor Shah Rukh Khan's film "Ra.One"

"ATTENTION !!! Someone using my fake ID and writing rubbish ..My ID is @SrBachchan .. fake ID being disgustingly used is @ SrBachhann," tweeted the "angry young man" of the 70s, on his official account.

The 69-year-old actor also used Twitter to warn the unknown poster: "BEWARE THE FURY OF A SILENT MAN ... !!!!"

"Fake ID of mine being used to write opinions on Ra.One .. I have not even seen the film and shall always wish the best for ShahRukh," Amitabh tweeted.

Later, he also wrote that "of late a great amount of negative, malicious, completely untrue remarks being written against me .. I shall bear with silence .. but, there's a limit to what can be said, a limit to what I can tolerate .. much is in my control .. think well before you malign me !!"

A clearly enraged Amitabh added that "and not just these comments on Ra.One ..many malicious, completely false accusations are being directed to me..I will not tolerate !"
