People bond over similar interests and hobbies and what led to the camaraderie between Bollywood director Milan Luthria and actor Randeep Hooda was their craze for horse riding.

"Randeep is an avid horse riding enthusiast and incidentally Milan too has an immense fervour for the sport. So when Naseeruddin Shah, a good friend of Milan, introduced him to Randeep shortly after he (Randeep) arrived here (Mumbai) from Delhi, the duo hit it off instantly thanks to their common passion for horse riding, " said a source.

"Milan also introduced Randeep to the Riders Club in Mumbai, " the source added.

Hooda also stars in Luthria's forthcoming underworld saga "Once Upon A Time In Mumbaai".
