PEAKY Blinders fans have called out a timeline plot hole from the first episode during a corrupt police take down.
The BBC drama began back in 2013 and saw Sam Neill play Inspector Campbell, who arrives in Birmingham to deliver his own brand of law and order.
Inspector Campbell is tasked with finding the missing consignment of guns from the Birmingham Small Arms Company factory, and quickly warns his team against any further bribes from the notorious gang lead by Tommy Shelby (Cillian Murphy).
But as he delivers his damning speech in front of a large ornate fireplace, one eagle-eyed fan noticed a blunder which shattered the illusion of the 1919 setting.
They wrote on online forum MovieMistakes.com: “When Inspector Campbell is making his speech to the officers, the board behind him has dates ranging from 1979 onward.”
It’s not the only plot hole viewers have spotted as they watch the series, either for the first or one of many times.
One viewer took issue with a season four scene which saw Tommy call his cousin Michael Grey in America.
Viewers of the series, based on an urban youth gang in the West Midlands in the late 19th century, have honed in on a season four scene which saw Cillian Murphy’s character send his cousin Michael Gray to America.
In the sixth episode of the instalment, Tommy orders Michael to tackle family business overseas, with hopes he could also tap into the booze industry in New York.
Being banished Stateside is also a punishment for Finn Cole’s character for betraying Tommy and while his journey to the US was perfectly do-able, viewers stated a phone call regarding his destination was not.
Scenes show Tommy picking up his black telephone to make a call to America – something viewers have stated would have been impossible to due in the time period in which the show is set.
One viewer wrote of on MovieMistakes: “Tommy makes a call during the episode to the USA.
“There was no system for international calls in 1926 for the general public, that was only introduced in 1927.”
The first Transatlantic phone call in fact took place on January 7, 1927, between president of the American Telephone & Telegraph Company, W S Gifford and secretary of the General Post Office of Great Britain, Sir Evelyn P Murray.
Peaky Blinders seasons 1-5 are available on BBC iPlayer.
