Mumbai, Jan 31 (IANS) They play antagonistic villains in "Agneepath" but in real life, Sanjay Dutt and Rishi Kapoor have discovered a new warmth and friendship that goes beyond the success of a collaborative film.

The last film they had done together was "Sahibaan" 18 years ago. Now while working together in "Agneepath", the two actors seem to have discovered a mutual fund of fondness.

Sanjay's new friendship was evident when on Saturday night he simply walked into Rishi and Neetu Kapoor's Pali Hill residence with his wife Maanyata with a bottle of wine to celebrate their mutual success in "Agneepath".

When we contacted Rishi to confirm the impromptu party, he said: "On Saturday night Dalip Tahil who loved me in 'Agneepath' came home. A few of my friends were already here. And lo and behold! In walks Sanju and Maanyata for an impromptu celebration. It was very sweet of him. We were two villains rejoicing our villainy together."

The on-the-spot party went on till the wee hours of Sunday morning with some of Rishi's close friends joining in. At some point during the evening Ranbir also joined his dad and Sanjay.

The Dutts left only after extending an invitation to the Kapoors to join the Dutts at a party on Sunday evening.

Incidentally, Saturday night also saw Hrithik Roshan, who plays the male lead in the new version of "Agneepath", hosting a party to celebrate the success of the action drama, which has been directed by Karan Malhotra and produced by Karan Johar.
