'The Big Bang Theory' could have gone on for two more seasons if Jim Parsons hadn't decided to leave.
As per one of the key crew members of the series, The Big Bang Theory could have carried on for at least "two more years."
The long-running comedy came to an end last year after 12 seasons, while production manager John Shaffner reported there were ambitions to produce several more seasons before Sheldon Cooper star Jim Parsons wished to depart.
"We got up and left and they started doing the table read and somewhere during that time word had got out that it was the last year. The news that it was ending had been leaked because Warner Brothers had prepared a proper roll-out of explaining it to everybody, but the cast didn't know."
Shaffner went on to explain Jim Parsons had been in touch with co-creator Chuck Lorre over the hiatus week and revealed he wouldn't be returning.

The Production Manager continued, "And Chuck had always said if one member of the cast left the show then the show would have to end. Warner Brothers and CBS wanted to sign for about two more years."
John was back in the office and he found out about what had transpired. He went down to stage where he saw Leonard star Johnny Galecki and Penny actress Kaley Cuoco in the comic book store and they were just hugging each other and crying.
