Big Bang Theory actor Kunal Nayyar cleared up a behind-the-scenes illusion.
During the interview, when talking about The Big Bang Theory, host Tim Lovejoy asked Nayyar how they pulled off scenes that showed the characters walking up and down stairs in their high-rise flat.
Nayyar then said that the show’s stars would have to remain in place while the set was changed.
The actor played Raj Koothrappali in the hit sitcom, which ran for 12 seasons in total.
