'The Big Bang Theory' series finale is close, teases actor Kunal Nayyar

The end for popular U.S. sitcom "The Big Bang Theory" seems to be quite close, or at least that's what one of the show's stars, Kunal Nayyar, feels. The 34-year-old actor, who plays the lovable Rajesh Koothrappali, recently said the fate of the show post Season 10 is uncertain as of now.

Speaking to Bang Showbiz last week at the Asian Awards in London, he was quoted by the Hamilton Spectator as saying: "We have one more series in our contract, that's Season 10. Other than that I don't know. But I'll keep doing it for as long as they will have me."

Nayyar added: "We could all have walking sticks doing 'The Big Bang Theory' Season 20. I think realistically there's less time left now than there was on the show before. Maybe it will go to 11, 12 or 13. I will do it as long as I can. But I think it is somewhere in that range."

"The Big Bang Theory" premiered in 2007 and soon struck a chord with viewers worldwide, making Nayyar and his fellow cast members, including Johnny Galecki, Jim Parsons, Kaley Cuoco and Simon Helberg, among the highest paid TV actors in the world.

Nayyar spoke about the show's end drawing closer earlier this year as well, during a podcast with Indian comedy collective "AIB." He said while the cast and crew were filming the ninth season, they all somewhere had an inkling the long-running sitcom's finale is in sight.

Nayyar also said he feels really lucky to be a part of "The Big Bang Theory," and gave due credit to the show's writers who, according to him, are "incredible story-tellers."

"You know I wake every day and get a script and I open it and it's like Christmas morning, because I'm just so excited to read it, the writers never let us down, they are such incredible story tellers and they have evolved these characters so beautifully. Sometimes you don't get the time to do what you want but we've had so much time and hopefully we'll have a little bit more. I just trust the writers. [sic]"
