Amitabh, 70, went Thursday to shoot an ad at the studio, built by Mehboob Khan in 1954. The actor praised the late filmmaker's love for cinema.
"Never trained or knowledged himself (Mehboob Khan) in the art of filmmaking, was not educated enough to speak the English language, was a paltry seller of goods, I am told, and worked at odd jobs in the studios and because of the love of cinema became one of the most prolific makers," Big B wrote on his blog late night Thursday.
"His dynamic confidence knew no bounds. He accomplished that which many other learned did not," he added.
Amitabh also mentioned his personal memories attached with the studio and says he has lost the "count of the number of films that I have shot there".
"My first meeting with Sunil Dutt saheb, when I came for a screen test in 1968 through the courtesy of Nargisji, in the dubbing theatre, where he was dubbing for 'Padosan'."
"The studio, buzzing with excitement with several shootings, and the stars in all their glory drifting in and out. To be told of the stories of the greats that worked and spent most of their time inside - Dilip saheb, Nargisji, Sunil Dutt, Dev Anand...the list just goes on," he wrote.
