In an interview with The Hindustan Times in which he discussed his current film and TV commitments, Johar said that the Jab Tak Hain Jaan star redefined love in cinema.
"I think [Shah Rukh Khan] was the one who redefined words like 'pyaar' (love) and mohabbat in Hindi cinema of the '90s and the 2000s," Johar claimed. "So even if he dons his lover boy avatar 10 years down the line, he can somehow pull it off!"
While Shah Rukh will reportedly star in Dharma Productions' next project - an action movie with Sanjay Dutt - the Student of the Year director said that he couldn't envisage any single project that could contain Shah Rukh, Salman Khan and Aamir Khan.
"If I make such a film, I'll end up in a hospital," he laughed. "We can't make an Amar Akbar Anthony out of them. There aren't many stories available that can absorb three distinct superstars like these."
The 40-year-old director is preparing for the release of Student of the Year, his first directorial project that does not include Shah Rukh Khan.
Johar, who is also a judge on India's Got Talent and Jhalak Dikhhla Ja, said that he is able to manage multiple film and TV commitments due to the fact that he is unmarried.
"When you aren't married and don't have children, you have a lot of time on hand," he explained. "Time becomes a constraint for a family guy. I'm free and to top it, I have a very accommodating mother. So it's easier for me to produce and direct a film and be a part of TV shows too."
The director revealed the third song 'Vele' from Student of the Year on Twitter today.
