Filming for season 8 of The Big Bang Theory has been delayed further, due to contract negotiations involving five of the show's stars.

The issues are said to be due to salary negotiations for Kaley Cuoco, Jim Parsons, Johnny Galecki, Kunal Nayyar and Simon Helburg.

Warner Brothers issued a statement regarding the delay, saying: “Due to ongoing contract negotiations production on The Big Bang Theory, which was originally scheduled to begin today, has been postponed.”

Uh oh, this does not sound good! We hope they can sort the issues soon and get back on our screen in usual hilarious fashion!
