Mumbai, Jan 24 (IANS): Stanley Tong, the director of the much awaited Indo-China film "Kung Fu Yoga" featuring Jackie Chan, said it is very difficult to work with the iconic film star.

"It is not easy to work with Jackie Chan as he always wants to do something different in each of his films. At times, you go run out of ideas," Tong told media here during the press conference.

"In last 25 years, every time I had to come with a new action sequence and that quite tough. Since there are many car chasing scenes had happen in past, we wanted to try something new and different; there came the idea of shooting with a lion inside the car," he said.

The director was present along with the legendary Jackie Chan, Sonu Sood, Amyra Dastur, Disha Patani among others as a part of a promotional event of the film "Kung Fu Yoga".

The story of the film is based on the lost Magadha treasure of India in Tibet. There is a reference of history that Tong enjoyed exploring while scripting and shooting the film, which widely took place in India and Beijing and some parts in Dubai and Iceland.

Sharing his shooting experience, Tong said: "I love India, I came to India for the first time in 1993. That time, I was shooting in Hampi (Karnataka) and this time during the shoot of "Kung Fu Yoga" I explored various parts of Rajasthan."

"I loved the culture and its beautiful architectures and history. In fact, the film is based on a historical story so I had to do some research work on that," he added.

The film is scheduled for release in China on January 28 and in India on February 3.
