Bachchan, 71, feels that the Farah Khan directed film, which stars son Abhishek and Shah Rukh Khan in pivotal roles, is an exciting project as he watched the few shots of the movie.
"Farah Khan and Shah Rukh show me some rushes of 'Happy New Year' and it looks so grand and big and exciting... And lots of fun..!!," Bachchan posted on his blog.
Bachchan also recalled his earlier days of filmdom in the studio.
"So many memories of the films made here and shot under exciting and at times strange circumstances.. It was here that I was first brought to by the late Nargisji, when I was contemplating entering films. There is a recording studio on the first floor of a separate building, and Sunil Dutt saheb was dubbing for the film 'Padosan'...," he added.
