Bollywood superstar, Salman Khan, reportedly suffered health issues during the shooting of his much-awaited movie, Tiger Zinda Hai.

During the shooting schedule in Austria, the 52-year-old suffered from health issues and struggled to give the perfect shot.

The film director, Ali Abbas Zafar, stated that due to freezing cold in Europe the team found itself isolated from the world.

In Austria, Salman couldn?t cope up with the conditions and developed a medical issue, which prolonged their stay in the country. Moreover, the cast wasn?t even prepared to deal with the freezing temperatures of the Austrian mountains.

"Shooting here meant dealing with unexpected situations. Literally a lot of pain had gone behind this sequence. Salman developed a health issue, but he still trained to film here and delivered on a tough action sequence,? said the movie director, according to Indian media.

"What we see onscreen might look a lot easier than it actually is. Sometimes, sequences like the ones shot in Austria can be difficult to achieve," Zafar added.

The movie has been shot in Morocco, Greece, Austria and Abu Dhabi.

Both Salman and Katrina play the roles of spies in the sequel to the 2012 blockbuster, Ek Tha Tiger.

The movie will hit the screens on December 22.
