"We are all wildlife enthusiasts. As far as my knowledge is concerned, sher is bigger than a tiger," Vivek told reporters in a light-hearted remark when asked about the two films.
When further queried about Salman's another film 'Sher Khan', Vivek said, "It's a good thing. The city is filled with sher (Sheronka shehar hai)."
He was speaking on the occasion of World No Tobacco Day at the studio of a radio station.
Bollywood actors Salman Khan and Shah Rukh Khan are seen as icons, but they are chain smokers. Vivek defends them, saying they acknowledge that smoking is a bad habit.
"They always say in all their interviews that they try to quit and it's a bad habit. The biggest problem with smoking is that it's a very individual decision. Whatever you do, people take their own time to quit cigarette," the 35-year-old said.
