The 71-year-old actor also spoke to the director and lead -- Deepika Padukone and Ranveer Singh -- over phone and congratulated them on their performances in the film.
"There is a certain joy in acknowledging the accomplishments of another... I did so today for Ram-leela, the film and its glorious cast and crew... With Sanjay Leela Bhansali, with Deepika and Ranveer and Supriya and Richa...
All that have made this film a most memorable experience for me..
"I have watched it 3 times over in the last 24 hours and still desire more... Those late hours that you have been noticing on timelines of this extraordinary medium, is so because of this most enjoyable activity of mine... So I wrote to them and sent them flowers and spoke to some and the delight that it gives me in doing so cannot be explained...," Bachchan posted on his blog.
Bachchan, who has worked with Bhansali in Black, said he is happy with the future generation of Bollywood.
"I relish the professionalism of those of this generation ... I am in awe of their accomplishments in such short period ... the sincerity and the absolute correct note in their early performances is incredible...
"How they are able to get the tone, balance and graph of the characters they play to perfection is a mystery to me, and I shall always laud them for it... They are truly the brightest future of cinema in India.. And I am filled with pride that I form a small portion of this fraternity..."
