But the experience of shooting it in Shimla was quite an adventure, says director Ayan Mukherji.
Parts of the Ranbir Kapoor and Deepika Padukone-starrer were shot in Himachal Pradesh as well as in Kashmir, and the weather conditions at the time of the shoot in January weren't great. However, the cast and crew had to deal with the situation, said sources.
There were especially food hassles.
"It was a big hassle to take food to that height, so everyone had to survive on eggs and instant noodles for a few days," said the source.
Likewise, in Himachal Pradesh, the weather conditions were a big problem for the entire cast.
"It was very cold. And the hotel in which Ranbir and Deepika stayed, had power cuts for several hours a day. There were no heaters either," the source added.
However, Mukerji said the adventure was totally worth it.
"Our first schedule was in Manali. We were depicting a trek in the movie, so we consciously chose locations that were offbeat and in the middle of nowhere. Jalori Pass, especially, was a crazy location. It was a steep, uphill climb to reach the location, a real trek of sorts.
"However, our shoot ended up being even more fun because of all this. It was perhaps the best schedule of the film," he added.
The film, which also features Kunal Roy Kapoor and Kalki Koechlin, is slated to release May 31.
