The 60-year-old actor also complimented Rakeysh Omprakash Mehra's "Mirzya" by calling it "breathtakingly beautiful and stunning".
"Breathtakingly beautiful and stunning teaser of #Mirzya. Congratulations @RakeyshOmMehra and Welcome @HarshKapoor_ :) http://bit.ly/Mirzya-Teaser," he tweeted on Thursday.
"Mirzya" is being touted as the biggest launch vehicle for newcomers Harshvardhan and Saiyami Kher.
The movie, set in Rajasthan, will be a tragic love story but will present a modern take on folklore.
