It is indeed tough time for Yash Raj Films. We hear that after strings of flops Yash Raj's upcoming films Chak De India and Lagaa Chunari Mein Daag are also undergoing some problems.

According to sources a huge tiff broke on the sets of Chak De India between the lead star Shahrukh Khan and the director Shimit Amin resulting in SRK's walkout.

"Shimit has tendency to shoot the same scene over and over again, even when everyone present there could see that a take was fine, really got on SRK's nerves," says a source on the sets.

Another major difference arose during the post production of the film when director Shimit approved the earlier promos of Chak De India which was screened with Jhoom Barabar Jhoom.

Apparently SRK was not satisfied with the earlier promos as he felt that it was not up to the mark. Nonetheless the promos were released but after it received a poor response from audiences, they were immediately pulled out. Now the new promos will soon be aired.

However the Yash Raj spokesperson denies that there were any earlier promos, she says, "There were no pulling out of any promos. We had a music video for the film along with Jhoom. There will now be one promo along with Partner and a new music video on television."

Chak De's other problem is the Women's Hockey Association who have been demanding a screening of the film prior to its release.

President of the Women's Hockey Association of India, Vidya Stoke says, "We want to see the movie before its release. Yash Chopra sought help from us and we were more than happy to help them thinking that it would create awareness about the sport in the country. They took a lot of inputs from us."

The film is based on a girl's hockey team and Vidya claims, "we need to have an idea about how they have portrayed women's hockey in the film. If they are portraying us in a bad light, we are going to take serious action against them."
