Tiger Zinda Hai director Ali Abbas Zafar says stars Salman Khan and Katrina Kaif's on-screen chemistry is 'sizzling'. The duo have paired up after five years--they were last seen together in Ek Tha Tiger--and have shot a huge dance number, Swag se karenge sab ka swagat, for the sequel Tiger Zinda Hai.

"Everyone already knows that both Salman and Katrina have this unspoken sizzling chemistry on screen, and this song exploits it in the most beautiful way," says Zafar. The track has 100 dancers, including trained ballerinas, hip-hop and Afro-dancehall dancers from Greece, France and Trinidad and Tobago.

"In Ek Tha Tiger, everyone had loved their chemistry, so for us it was a challenge to push the envelope in terms of how they look and how the song was going to be. A lot of attention has been given to how they are styled and the locations," he adds. 

Zafar says Salman and Katrina are looking the best they have looked together. "We are absolutely thrilled about that," he says.
