Kolkata: Megastar Amitabh Bachchan, who will be seen in a wheelchair in his next film "Wazir", says it was physically more challenging than his other roles.
"I think every role is challenging but physically perhaps a little more because you do not have feet to express yourself but two wheels of the chair," he told the media here.
"Wazir" produced by Vidhu Vinod Chopra and directed by Bijoy Nambiar, stars Amitabh Bachchan, Farhan Akhtar, Aditi Rao Hydari and Neil Nitin Mukesh.
To hide his feet, Big B said the team opted for visual effects.
"I am not very conversant with visual effects. They used to ask me to wear black socks and draw marks on them. My feet used to be tied. I did not think it was really cumbersome. It adds to your performance," Bachchan noted.
Infact, Chopra made sure the wheelchair chosen for Bachchan was the perfect fit.
"They went through 40 to 50 wheelchairs to find the ideal one," said Bachchan.
The 73-year-old star acknowledged that colleagues-turned-politicians Shatrughan Sinha and Vinod Khanna have better career graphs.
"All my colleagues are working. Shatrughan Sinha and Vinod Khanna are two exceptional examples. They started off doing villain roles and they were so good they became leading men but then they joined politics and succeeded there as well. Their career graph is better than mine," he added.
Talking about his recent films with the current crop of directors, Big B described Shoojit Sircar's "Piku" as a "delightful experience".
"The music was exceptional. With all due respect to the kind of music we hear today, it came as a huge surprise because it was so pure, so simple and very effective because it is the kind of music we do not normally associate with films and the background score was phenomenal," Bachchan observed.
