The director, fondly called Balki, is helming "Shamitabh", which also features Dhanush and marks the Bollywood debut of southern superstar actor Kamal Haasan's daughter Akshara. The film is expected to hit the screens February 6, 2015.

Big B, who has worked with Balki in films like "Cheeni Kum" and "Paa" in the past, sported a rather pensive look with a beard in the black and white sketch.

"YES...notice the 'Balki nisation' of the Blog, as in the years within the Balkans... hehehe...Some times it's good to laugh at one's own stupidity...I just presented a sample! Love,"  Big B posted on his blog

The 72-year-old star, who was busy shooting for Shoojit Sircar's film "Piku" in Gurgaon, is now headed to Gujarat for the shoot of "Shamitabh".

"It's departure time in the morrow and more of the film that Balki asked me not to talk or print about, in the extensive lanes of Gujarat, away from the hurly-burly."

"Soon that shall be over too...and I have no idea why these words are coming to you in bold...they seem to have a mind of their own," he posted.The actor, who has rolled out several popular films like "Black", "Deewaar", "Agneepath" in his over 40-year-old career, also posted a poem with his "Shamitabh" movie look.
