Calling the letter his "award", an overwhelmed Ranveer took to Twitter to share the picture of the note and a bouquet Bachchan sent him after watching the Sanjay Leela Bhansali period drama.
"Mujhe mera award mil gaya (I have got my award) @SrBachchan," the actor, who is receiving rave reviews for his portrayal of Sultan Alauddin Khilji in the magum opus, captioned the tweet.
Ranveer, 32, also received a handwritten note in 2015, after Bachchan had watched "Bajirao Mastani".
Featuring Deepika Padukone in the lead, "Padmaavat" also stars Shahid Kapoor, Jim Sarbh, Aditi Rao Hydari and Raza Murad.
