Revealed: What Bollywood's Big B saw at Roman Abramovich's mansion

It would take some doing to impress the Big B of Bollywood - Amitabh Bachchan, certainly in terms of opulence.

Given that the legendary Indian actor has a few hundred million quid of his own and has seen life in the fastest of lanes over the years – hobnobbing with the opulent elite of the world.

This is why it is worth considering the effect Roman Abramovich, owner of Chelsea Football Club (among other things) had on Amitabh.

Bachchan is in Cannes for the film festival that opens today (May 15) with the screening of the Baz Luhrmann film 'The Great Gatsby' and will walk the red carpet.

But this is what he tweeted: "GOSH !! Just back from an eye opener evening ! Dinner at the Palace of billionaire Roman Abramovich, here in Antibes, Chelsea owner, and many other businesses, in the company of entire cast of 'Great Gatsby' … added attraction Martin Scorsese, Ang Li ! And what a residence ! Unbelievably aesthetic opulence … rarest of paintings, art decor and just every facility you could ever imagine ... place belonged to exiled King Edward of Windsor .. 100 acres of property, immaculate lawns and bushes and trees, each blade of gras cut the same size, and miles of bushes without a leaf out of place ... cannot describe the feeling !! Prada invite !"

He is all set for the countless number of events lined up, "Getting to bed ... early call tomorrow and busy ... media first then red carpet then after party and all compulsory," he tweeted.

He continued, "...Sometimes you imagine in disbelief that life shall present itself in the form that you may have yearned for ! And then suddenly one day it happens .. it did tonight .. and it is all so un imaginable !! Here at Cannes for opening of Great Gatsby and the energy and excitement of International greats in the field of entertainment .. un forgetable !!"
