The 70-year-old, who was last seen in "Satyagraha" will reprise his role as a friendly ghost in the movie.
The actor shared the update via microblogging site Twitter.
"Another new film 'Bhootnath 2' starts tomorrow (Wednesday) and as my make up Deepak Sawant would say 'ek aur meter down ho gaya' (another meter down)," Big B posted in the early hours of Wednesday.
Even after so many years in filmdom, Big B is nervous before starting a fresh project.
"Then there is the look test for 'Bhootnath 2' starting shoot tomorrow. First day of new projects are such a fright! 'Bhootnath'," he added.
"Bhootnath 2" will be directed by Nitesh Tiwari and produced by T-Series. It is expected to release in summer 2014.
