"I work tomorrow... A shoot for R Balki... For the film he does with Akshay Kumar... A special appearance for a few minutes...
"Balki does carry his sincerity at every step of his creativity, and must have my presence in some form or another, and so here I am more of which shall come by when the act of the morrow is done," Bachchan wrote.
