'New Tricks' writer Julian Simpson has hit back at Amanda Redman's claims the show has become "bland".
The actress claimed in an interview the new series of the BBC crime drama - which follows the work of the Metropolitan Police Service's Unsolved Crime and Open Case Squad - has become duller because writers sometimes think people are stupid, but Julian has claimed actors should not get involved in such discussions.
He wrote in a series of posts on twitter: "I was going to be writing today, instead I'm just going to hand the actors a pad and pen. I wish I'd learned this 15 years ago.
"A New Tricks I wrote and directed airs on Monday. I can tell you EXACTLY how much of it the actors wrote: not a f**king comma. (sic)"
He also hinted not all actors are as good at their jobs as they should be, writing: "Wait a second... *smells a rat* if certain actors re-wrote the scripts, how come they don't know the lines better? (sic)"
However, he added he generally got on well with the cast of 'New Tricks', which also includes Dennis Waterman.
He said: "Worth saying that I get on phenomenally well with the New Tricks cast. Just don't appreciate actors speaking out of turn and they know that. (sic)"
