Mumbai: After appearing in a dance number together in Farah Khan’s ‘Tees Maar Khan’, Katrina Kaif and Salman Khan are back together in a Yash Raj’s new flick which is said to be a romantic thriller. Produced by Aditya Chopra, the film is written and directed by Kabir Khan of 'New York' fame.

I am doing Kabir's film...Katrina is there in the film. But it is not a superhero film. I can't say what the film is about. I am honoured to work with Yashji who has worked closely with my father in the past," Salman said.

"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," he said.

Titled 'Ek Tha Tiger' it is Salman's first film under the YRF banner and will go on floors in early July and release in mid-2012. The music will be scored by Pritam.

Yash Chopra described the project as a '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. Over the years, Salman has become a very matured and talented actor and both he and the beautiful Katrina have a tremendous connect with their audiences."

Kat will be seen romancing with the ‘Dabanng’ superstar after a gap of three years.

Salman and Katrina were first seen together in 2005 in 'Maine Pyaar Kyun Kiya', directed by David Dhawan. The couple again shared screen space in Dhawan's 'Partner' starring Salman and Govinda in the lead roles although the star was paired opposite Lara in the 2007 blockbuster.

A year later in Subhash Ghai's 'Yuvvraaj' the two actors were paired opposite each other but the movie bombed at the box office. (Now, Salman would be seen opposite Asin in Anees Bazmee’s 'Ready', a comedy that releases on June 3. "I am all looking forward for 'Ready'. I just hope we stand up to the expectations," he said.

The 45-year-old actor will also be seen in brother-in-law Atul Agnihotri's up-coming romantic-action film 'Bodyguard' opposite Kareena Kapoor, slated to release on August 31 this year.
