I read Tony Warren’s autobiography a few years ago. He said he regrets the Duckworths/Rovers storyline, he’d been enthusiastic about it but it just didn’t work out. He also said that Bill Tarmey and Elizabeth Dawn expressed doubts when they heard what was in store for their characters.
Lynne Perrie said that some younger actors resented Betty Driver’s salary. She was also quite scathing about Warren Jackson (Nick) - but despite that, he and Helen Worth were the only cast members who attended her funeral.
