Fans of the beloved CBS sitcom 'The Big Bang Theory' are beginning to become worried about the effect these recent behind-the-scenes issues could have on the show's eight season, which is scheduled to production on Wednesday (July 30th).

The cast of 'The Big Bang Theory' are still negotiating new contracts

Warner Bros., the producer of 'Big Bang,' announced that filming has been delayed because the cast, Jim Parsons, Johnny Galecki, Kaley Cuoco-Sweeting, Simon Helberg and Kunal Nayyar, are still negotiating new deals.

"Due to ongoing contract negotiations, production on 'The Big Bang Theory' - which was originally scheduled to begin today - has been postponed," the film studio said in an official statement on Wednesday.

This past March, CBS ordered three more seasons of 'Big Bang,' and will therefore take the hit show to ten seasons, until the 2016-2017 television calendar, which puts it on the same par as the universally loved sitcom 'Friends'.

And it seems all the original cast want to be paid the same amount the 'Friends' cast was as well. For season 7, the big three, Leonard, Sheldon and Penny, played by Johnny Galecki, Jim Parson and Kaley Cuoco-Sweeting, earned $350,000 per episode, but now the trio are reportedly demanding up to $1 million per 22 minutes of televisual viewing.

But even though production has been halted, it seems higher-ups within the show are confident their contracts will be successfully negotiated sooner rather than later.

"It will be fine," Chuck Lorre, the show's creator, told E!News earlier this month. "Warner Brothers has done this before. Everybody should be very successful and happy and rich. They earned it. It's a great cast. Great cast. It's their time."

While at the 2014 TCA Summer Press Tour, CBS' Nina Tassler also said, "We're feeling very confident that everything will work out. These deals manage to get done miraculously somehow year after year."

The eight season of 'The Big Bang Theory' is set to premiere on September 22nd.
