Actor Amitabh Bachchan, who will soon be seen in Wazir, said that his role in the film was physically challenging.
"I think every role is challenging. But physically, perhaps this was a little more because you do not have feet to express yourself but two wheels of the chair," said Big B.
Directed by Bejoy Nambiar, Wazir features Farhan Akhtar and Aditi Rao Hydari, apart from Big B. (Also Read: Farhan Akhtar Reveals The Experience of Recording Song With Big B)
"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 that it was really cumbersome. It adds to your performance. They went through 40 to 50 wheelchairs to find the ideal one," added Big B.
Nevertheless, Mr Bachchan said that his colleagues 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 with villain roles and they were so good that they became leading men but then they joined politics and succeeded there as well. Their career graph is better than mine," he added.
Big B, who featured in Shoojit Sircar's Piku this year, said that it was 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. This is because it is the kind of music we do not normally associate with films. Also, the background score was phenomenal," he added.
