Rishi, 62, who was last seen in "Bewakoofiyaan", said he finds his look quite "cool".
"This picture is from "Sanam Re" play an eighty year old man. Cool! (sic)," Kapoor posted on Twitter with a picture.
In the Divya Khosla Kumar-directed movie, the veteran actor is playing a grandfather. Produced by Bhushan Kumar, "Sanam Re" also stars Pulkit Samrat, Yami Gautam and Urvashi Rautela.
Apart from "Sanam Re", Rishi will be seen playing the role of a father to Abhishek Bachchan in "All is Well".
