"We had a shooting schedule in London. It was extremely nice.

The weather was cold out there but we had a nice time," Katrina told reporters here last evening at the launch of a book based on one of her films, Rajneeti - The film and Beyond . "We think of Yashji as a senior and young at heart man.

But you have to be on sets to understand how sharp he is. He picks up small small things like something was disturbing me or something with my mood.

He used to pick up all that which no one else does. He is a very special person.

" Shooting for the untitled film, which also stars Anushka Sharma, started in the third week of February in London. Katrina also happened to injure herself on the sets of the film, which she thinks is a good luck sign.

"I hurt myself on bike. While I was getting off the bike I hurt my leg as I had it on silencer.

But in a way it is a good luck sign," Katrina said. "Every time I hurt myself during films, it turns out to be good thing.
