Kangana Ranaut is all released fun and feisty in "Tipa", the latest song to be from Vishal Bhardwaj's 'Rangoon'. The track, choreographed by Farah Khan, has the actress dancing on an open train bogey.

Talking about her looks, the actress revealed, "Vishal sir has a habit of reinventing his actors. Before this, no one has explored my beauty on screen. I was given a fake nose in Revolver Rani and a set of fake teeth in Tanu Weds Manu Returns. Throughout the look test, Vishal sir kept saying, 'Make her look prettier than she already is'. We've kept the look very authentic, including the curls in my hair."

"Tippa" was shot in Arunachal Pradesh, and a rail track was specially created to shoot the number. Though the location was picturesque, it was quite remote and the team faced many challenges, including lack of mobile network and toilets.

That's not all. Eager to see Kangana dancing, huge crowds would gather on the location, with some crazy fans even running behind the train.In a bid to avoid being mobbed, the crew finally started shooting early in the day, much before the village would wake up.

About the challenges of shooting in Arunachal Pradesh, she added, "The phone network was really bad. It got especially difficult when I had to deal with a legal issue back home in Mumbai. We'd drive 20 kilometers to receive calls. But otherwise, when I am working, I love non-network zones, especially places like Arunachal Pradesh, which are so beautiful. They bring me closer to the people I work with. Yes, we didn't have loos, but I am a mountain woman, so I could pee behind the rocks and be cool about it. Saif Ali Khan and Shahid Kapoor were sporting, too."

The period drama, set in World War II, has Kangana play Miss Julia, an artiste who embarks on an expedition to buoy the spirit of the soldiers.
