Richard Osman's Thursday Murder Club book series is one of the most successful of recent years - more than 10 million copies have been sold, all four books have broken UK sales records and the fifth instalment will be released in the autumn.
It's no wonder, then, that the star-studded cast of the film adaptation would be somewhat nervous about how fans will receive the movie.
Speaking to the BBC, Pierce Brosnan says the nerves have ramped up over the past few weeks. "It's a huge responsibility when you have an audience and the world waiting to see these characters."
The film sees the usually well-groomed Irishman transform into a bearded Ron, the gregarious one-time trade union leader turned unlikely amateur sleuth, in a new Netflix movie based on the first book in the series.
Brosnan also admits he first thought of another actor when reading the part of Ron.
