"I feel strongly that the interval point in cinema is a great point. We all know that in second half of most cinema things speed up. That's my feeling for Indian economy," he said.
"When it comes to India, I'm hoping for a glorious second half and a great innings ahead," he added.
"Here there are so many negative and pessimistic voices about the economy," he said. "In Europe they are hoping... their economic growth is flat and not negative."

The economy, he said, would grow at 6.7 per cent as opposed to previously projected 7.3 per cent, according to RBI.
"That's still not flat, we are still on our way up. And I feel very strongly that just like our films, our narrative is dramatic, sometimes melodramatic.
"It always has a tinge or humour but eventually there is a happy ending - that's the way our cinema is. That's pretty much my hope the narrative of India would always be," he said.
The growth would peak to 7.7 per cent in the fourth quarter of the fiscal ending March 2018.
Later at a press briefing, Johar said, "I feel that sometimes we tend to get extremely pessimistic about our environment and our economic political and social stability."
Stating that he is someone who is exceptionally optimistic, he said India has stable political governance with a majority government.
