"The 'Bhoothnath Returns' promotions now take up all my spare time and travel. There is much to be done and there are time constraints. Radio, television, print, channel shows, visits to cities, premieres," the 71-year-old, who will make appearance on shows like "Boogie Woogie" and "Comedy Nights with Kapil", posted on his official blog srbachchan.tumblr.com.
He also mentioned that "there is a mountain of film scripts" that need to be read and decided upon.
In the coming months, he is looking forward to "R. Balki's rather unusual and exciting film with Dhanush and Akshara starting work next month, TV serial shooting in progress and we hope that it comes on soon, Shoojit Sarkar's film 'Piku' with Deepika (Padukone) and Irrfan Khan, starting work by June-July, simultaneously starting preparations for 'Kaun Banega Crorepati (KBC)'".
"And in between 'KBC' to find days and time for Vidhu Vinod Chopra's production, with Farhan Akhtar. There are a few more that have been green signalled - an Abbas Mustan film, a Rumi Jafri film and a few more with other distinguished directors and two offers from overseas," he further posted.
Amitabh also has a desire to show his skills on the stage.
"Amongst all this, there shall be a desire to perform on stage with recitations from my father's works, and to be able to take it on an extended form to cities within and without India. Then there is all the charity and philanthropic work, which shall involve personal looking into, to ensure proper execution and delivery," he posted.
Recently he was a bit under the weather. He underwent a CT scan and was advised bed rest for a few days, but now Big B is raring to go.
"Health issues shall always remain - we are perishable entities, are we not? ... but for the moment the one that had jolted me recently has been taken care of ... sufficiently taken care of, to enable me to start gyming again ... felt good after a two-hour session," he posted.
