David Bowie was a huge fan of the show and gave permission for music from his final album to be featured in Series 3. Steven Knight, the shows creator, learned of Bowie's interest after the singer sent a photo of himself with razor blades in his cap to lead actor Cillian Murphy. Knight revealed: "I got in touch with his people, who came back straight away and said he was a big, big fan." Bowie later sent a representative from his label to provide an early hearing of his final album Blackstar a week before its existence was made public. "And then on the following Tuesday we heard that he'd passed away. It seems that his people were keen to establish that we could use it before he died."

Despite the shows claims, the Peaky Blinders were strongest in the 1890s. By the 1920s the predominant gang in Birmingham was 'The Birmingham Gang' which had its roots from the pre-war 'Brummagem Boys' gang.
While the show has often received criticism for the seemingly inaccurate accents, much of the cast and crew have confirmed that they are historically accurate. The 1920's dialect for Birmingham, England was said to be slightly different. Helen McCrory has even stated the accents are authentic 1920's Birmingham dialects. Despite this, many UK viewers believe that the accents are watered down versions of proper dialect to appeal to US viewers.
Although set in 1920s Birmingham, the show is mostly filmed around Liverpool and Merseyside and in London. Wherever possible and appropriate, scenes are shot in Birmingham and the West Midlands (such as The Black Country Museum in Dudley) however there are very few areas of Birmingham left that still resemble the period environment required.
The show's title is derived from the gang practice of wearing flat "peaked" caps, which they could then see under due to the shorter brims compared to the hats usually worn by more distinguished gentlemen.
The real Peaky Blinders were unlikely to carry razor blades in their hats since in the 1890s, when the gang was really present, they were considered a luxury item and too expensive for the gang to own. The idea of the razor blades hidden in caps has its roots in John Douglas' novel 'A Walk Down Summer Lane'.
