Salman Khan and Katrina Kaif are coming together for Yashraj film`s romantic thriller `Ek Tha Tiger`.

The movie has been directed by Kabir Khan of `New York fame and produced by Aditya Chopra, who has also written the story.

The screenplay and dialogues have been written by Kabir Khan and Neelesh Misra. Aseem Mishra, who has worked with Kabir on `New York`, will be the DOP. The music will be scored by Pritam.

The 45-year-old actor, who is working with the banner for the first time, says the project is going to be a huge challenge for everyone.

"In the past Adi and I have met a few times on various projects but somehow, when Kabir and he came to me with this particular story, we all just knew that this was the one. It is a very ambitious project and will be a challenge for all of us, but that`s exactly what makes it such a big draw. I`m honoured to be working with Yashji, who has worked so closely with my dad in the past," Salman said in a statement.

Yash Chopra, speaking about the project, said it was a very happy moment for him.

"Everyone knows my association with Salim saab, having worked together on `Deewaar`, `Trishul` and `Kaala Patthar`.

It is a very happy moment for me and YRF to have his son Salman with us for the first time," Chopra said.

The film starts shooting early July and is slated for a mid-2012 release.
