The 69-year-old actor said that filmmaker Manmohan Desai had introduced the concept of vanity vans and gifted him one too.
"At the studios these days, the largest space is taken up by the vanity vans for artists, talent, directors, writers... It was never like this in our time... Ok... Like earlier days! At times for an all night shoot, you just dozed off on the floor of the set... Getting a room was a luxury.
"But Manmohan Desai, the master, was different. He had a back problem and needed to lie down as he travelled to the sets, so he built himself a van where a bed could be placed and put up a television set inside, something that was unheard of...," the 69-year-old posted on his blog.
"And then within a few days presented me with one. It was not what vanity vans are like today... I put in a pull out make up tray with mirror, to do my make up in there and desperately tried to fix a music system within," he added.
Bachchan had teamed up with the maverick director many a times and has given hits like "Mard", "Coolie", "Naseeb" and "Amar Akbar Anthony". PTI NDS
