The 'Big Bang Theory' stars have demanded a pay rise.
The cast of the CBS hit show have reportedly refused to sign their contracts for the upcoming season until bosses agree to pay them $1m per episode.
Jim Parsons, Johnny Galecki, Kaley Cuoco, Simon Helberg and Kunal Nayyar are currently locked in a bitter battle with Warner Brothers TV as they are looking for a similar payout to the cast of popular sitcom 'Friends', which ended in 2004, according to Deadline.
Jim, Johnny and Kaley currently earn a reported $325,000 per episode, and bumping their wage up would make them the highest paid actors on US television, even beating TV favourites Ashton Kutcher and Jon Cryer from 'Two and a Half Men'.
The eighth season of the show is expected to go into production at the end of this month, but filming could face a delay if bosses and the cast don't reach an agreement within the next two weeks.
Meanwhile, the network recently announced that the long-running programme will continue for another three seasons at least, which means it will stay on screens until 2017, after proving to be such a hit with viewers.
