Saif will join Karan to host the 18th edition of the International Indian Film Academy (IIFA) Awards in New York next month.
The actor, who was present here on Monday along with Varun Dhawan and Karan for an IIFA 2017 press conference, said: "Film industry is incomplete without Karan Johar."
When mediapersons asked the reason behind making such a statement, Saif quipped: "'Baahubali...' Can you imagine our film industry without that? He is one of those arteries in the blood flow of the film industry."
Karan, who was sitting next to him, thanked Saif for saying that.
Looking back at his journey as a host, Karan said: "I realised I started hosting shows from 2000, which was a Filmfare award. It's been 17 years! I am glad that every year I have managed to get the job! The experience is always good, as I enjoy whenever I am on stage."
Karan's directorial "Ae Dil Hai Mushkil" is the front runner in the nomination pack of the 18th edition of the gala.
Is he nervous?
"It is great to win it when you win but if you don't, you should not care," he said.
Saif also said that he wants to host a show with superstar Shah Rukh Khan. He said: "It will be fun! He is so clever, I would live to host a show with him."
Varun, who was sitting next to Saif, said: "I would love to watch you (Saif) and Shah Rukh working together on-screen."
IIFA will be taking place at the MetLife Stadium, New York on July 14 and 15.
