When it comes to chemistry -- the male version at that! -- very few can beat the on-screen bond between Amitabh Bachchan and Dharmendra. We've seen it in movies like Sholay, Chupke Chupke and Ram Balram, to name a few.
They are very good friends offline as well.
On Dharmendra's 81st birthday, Amitabh Bachchan tweeted pictures that showcased their off-screen chemistry and wrote, 'Birthday greetings to dearest Dharam ji... love and affection !!'
