Indian star Amitabh Bachchan is furious after a mystery Tweeter set up a fake account purporting to be the famous Bollywood actor, and to make matters worse they don't seem too impressed with Bollywood sci-fi flick 'Ra.One'.

Bachchan has appeared in dozens of films since making his big screen debut in 1969's 'Saat Hindustani' and is involved with 12 movies to-be-released or already out this year alone. Although not starring in 'Ra.One,' he's good friends with the film's director Shahrukh Khan and was riled when his impostor, going under the Twitter handle @SrBachann, tweeted "Saw Ra1. What a Waste. Even the worst of Abhishek's like Drona were much better. May be Srk's mid age crises (sic).

" A furious Bachchan retorted "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 (sic)", going on to warn, "Of late a great amount of negative, malicious, completely untrue remarks being written against me... I shall bear with silence... but beware the fury of a silent man".

The 69 year-old went on to add, "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 .... Completely false accusations are being directed to me... I will not tolerate."
