Superstar Amitabh Bachchan is sporting a "phenomenal" new look in his upcoming home production "Paa", the make-up for which takes four hours, the actor wrote in his blog.

"My rituals today were guided by the extensive hours at the studio, a major portion of which were in front of the make up mirror, getting the face plastered with silicon," the actor said in a recent post on his blog.

"It took 4 hours for it all to come on and another hour to take it off. But may I say the results were simply phenomenal," the 66-year-old actor wrote.

The film also stars Abhishek Bachchan, Vidya Balan and Hurman Baweja in key roles.

The star is relying on a team of make-up artistes from abroad for his look in the film.

The film is being directed by R Balki of "Cheeni Kum" fame. The production of the film went on floors on March 2.

"The team of make up artists flown in from Los Angeles and carrying huge and important credentials were exemplary in their job. Professional to the core and committed to the last brush of paint on the face," Bachchan wrote.

"Paa", a film that Bachchan terms as an endearing address by Abhishek (Bachchan) to his father, is a part of the co-production deal between AB Corp and Reliance Big Entertainment.
