Comments from followers quickly poured in with many lamenting the casting choice of Ron, played by Pierce Brosnan. One fan wrote: "I just can't get behind Pierce as Ron. This trailer has done nothing to make me feel better on that score. Hopefully I'm wrong."

Another person agreed, replying: "I always imagined Ray Winstone as Ron when I read the books or Brian Cox. I got most of the others right though when I was guessing the who the actors would be." Someone else moaned: "Loved the book, and apart from Celia Imrie, I wouldn't have chosen any of these actors, so I hope it's up to scratch. I would've had Jim Broadbent, Penelope Wilton, Lennie James, Tim Spall types in there..."

In addition to Pierce Brosnan as Ron, who is descirbed as "a rash, alpha-male former union leader - and yet he still fits right in," Helen Mirren plays Elizabeth, Ben Kingsley stars as Ibrahim, and Celia Imrie portrays the exuberant Joyce.

The synopsis explains: "When an unexplained death occurs on their own doorstep, their casual sleuthing takes a thrilling turn as they find themselves with a real whodunit on their hands.
