"A little while ago I watched 'D-Day' a film made by Nikhil Advani, and have been simply overwhelmed by it. The story, screenplay, performance and execution has been outstanding," Bachchan wrote in his blog early Friday.
"There is a sense of great pride to not just see what we are seeing almost every week, but to just be in the company of this new generation, to live what they produce, to know how much of a difference they are making to our appreciative eyes and mind.
"May God bless them, and may they continue to bring joy and happiness to not just the connoisseur, but to all that witness the efforts of such a dedicated and determined set of youngsters," he said.
Bachchan said he envies the younger generation of actors for the varied roles they are offered now-a-days.
"I am in awe of them, and envy them and lament the fact that I am not living in their times, to have opportunity to be a part of their creativity and their brilliance," he said.
'D-Day' is a crime-thriller starring Arjun Rampal, Rishi Kapoor, Irrfan Khan, Shruti Haasan, Sandeep Kulkarni and Huma Qureshi in lead roles.
