Production on the next seasons was due to resume this week but contract negotiations have not yet been settled for stars Jim Parsons, Johnny Galecki, Kaley Cuoco, Simon Helberg and Kunal Nayyar.
All 5 are understood to be vying for a big salary increases.
Parsons, Galecki and Cuoco, who currently earn $325,000 per episode, are seeking up to $1 million per episode with a share of the show’s backend profits, something that creator Chuck Lorre has acknowledged he would like to see happen.
Helberg and Nayyar are negotiating together while co-stars Mayim Bialik and Melissa Rauch previously secured big raises.
The Hollywood Reporter notes the first table read scheduled to take place today did not take place, surprising the studio that believed the cast would turn up, with or without a contract.
“Due to ongoing contract negotiations, production on The Big Bang Theory — which was originally scheduled to begin today — has been postponed,” Warner Bros. TV said in a statement.
The cast was also no-show at Comic-Con, where for the second year in a row, but Jim Parsons appeared the day before the show’s panel for DreamWorks Animation’s Home, in which he has a voice role.
However Deadline also reports “I hear the postponement is for one day, and the situation would be evaluated day by day as the two sides continue to negotiate and are close to deals, something that could happen as early as today.”
