Kunal Nayyar, star of The Big Bang Theory, says the show may end soon

Series nine of The Big Bang Theory, which finished airing in the US a couple of weeks ago, brought the episode tally to more than 200.

The actors are back in the studio in August to start filming the tenth series of one of the world's biggest comedies.

But Kunal Nayyar, who plays Raj, has suggested the show could be ending.

"Look - next season, as it stands on our contract, could be the last season of Big Bang Theory," he said.

Speaking to an audience at the MCM comic con in London, he added: "To be completely honest…I know people are gonna want to know what happens after season 10. I don't know what's going to happen."

According to the Radio Times, he also asked co-star and panellist Melissa Rauch (who stars as Bernadette): "Melissa, are we going to do season 11?"

"I don't know - I'd love to," she replied. "We'll see."

He added: "If it were up to me personally, I would love to do the show as long as you guys would have us on the air."

It also looks unlikely the show will follow in the footsteps of Sex and the City, The Simpsons and The Inbetweeners and make the leap to the big screen.

"I mean it's a very difficult format to do for a movie, because you know we shoot in front of a live audience, a live studio audience, with four cameras," said Nayyar.

"So unless the movie was a two-and-a-half-hour sitcom version of The Big Bang Theory, I don't think we could ever actually do a movie."

There's one glimmer of hope for fans though.

"We could do it on stage…"

Nayyar is in London performing his new play The Spoils which co-stars, and was written by, Jesse Eisenberg.

You can watch them in an on-stage discussion at MCM.

In a separate panel the pair joked that Eisenberg could join the cast of The Big Bang Theory in the next series.

"I have told Kunal I want to be on The Big Bang Theory," said Eisenberg.

"But my one stipulation, I've told [producer] Mr Chuck Lorre this, is that I play Kunal's biological brother and no questions are asked."
