Watch: Explosive Peaky Blinders Series 5 Trailer

"There is God and there are the Peaky Blinders" says the opening line of the trailer. "We're on the ropes, who's gonna hang us now, ai?"

Within seconds, the short video drags viewers into the gangsters somber yet absolutely fascinating world, set in the aftermath of the Wall Street crash this season.

Capturing tensions, fear, explosions and relentless determination, the scenes featured are as intense and captivating as ever.

In a 'BBC's Obsessed with' podcast, Peaky Blinders creator Steven Knight gave another preview of the highly anticipated fifth season.

"There is a thread and a strand to it which is incredibly topical. Not thanks to me, but thanks to what was happening at that time. There are so many parallels," he said.

"It's the early '30s and it's the first stirrings of fascism and nationalism and populism, and there are particular politicians that were happy to stir that up and make use of it and get votes from it."

"And Tommy has to face that and it's part of what I feel will, hopefully, eventually be a rehabilitation of him, because when he comes across that, how's he going to react? Is he going to go with it? Is he going to oppose it?," he added.

Peaky Blinders fans went wild when Al Capone was name checked at the end of the fourth season. Many assumed that the role would be given to Stephen Graham, who had already played the iconic Chicago gangster a few years ago on Broadwalk Empire.

However, Knight cut the rumours short when he told the BBC that Graham has already been devised a role in the show but it isn't Al Capone: "We're proceeding with that, but not this series. Not Al Capone, I didn't want to go west. Once you go into Chicago gangster..."

"I referred to him last series, but I didn't want to go into that," he added.

Asked about potential Peaky Blinders guest stars, Knight said: "I don't know where that got out, but, yeah, fingers crossed on that."

"The amount of people who have come to us wanting to be in it is quite astonishing - and really good people. What I've tried to avoid before is turning it into a 'spot the celebrity', you know, because I think it's quite distracting sometimes.

"But someone like Adrien Brody is a great actor, obviously you want to put them in it, but I think now we're coming to the final two series, I'm going to relax and open the gates a bit because there's some amazing people who want to be in it, and I think 'Why not?'"

Addressing rumours which said that Julia Roberts is eyeing-up a role on the show, Knight said: "I don't know where that got out, but, yeah, fingers crossed on that."

More suspense and heart-stopping drama ahead!
