"In between all this trying to make efforts on taking up the offer of Komal Nahata for his Rajasthani film that he had proposed somedays ago," Big B posted on his blog.
"Language, is where I shall have to work most seriously - the Rajasthani language! Will make effort. Lets see!!" he added.
Komal Nahata is a trade analyst and he has also starred in the 2010 comedy "Tees Maar Khan".
Till date, the 68-year-old Bachchan has done just one regional film and that too a cameo in Malayalam movie "Kandahar".
