Hardy's son Louis, with his ex-girlfriend Rachael Speed, is now 6. When we met for Warrior back in 2011, he was about to head to Australia to shoot Mad Max: Fury Road and having to leave his child for months was already devastating him. "This has come at a time in my life when I'm actually settled," he said. "All this was a fantasy before but now that it's happened, I can't actually get past the idea of being away from my child for 11 months. I'm going to be in denial until I'm on the plane."
As it turned out, the Fury Road shoot ended up being postponed until summer 2012, but Hardy's itinerant lifestyle only became more hectic in the interim with his rampant post-Bronson ascent. Hollywood beckoned, Hardy answered. Somehow, he even ended up in a Reese Witherspoon action-comedy directed by McG, This Means War, in which he looked less relaxed than a penguin in a shark pool.
The Drop is a far more comfortable fit for Hardy. It is directed by the Belgian film-maker Michael R. Roskam, whose 2011 crime drama Bullhead, about a steroid-addicted cattle farmer, was nominated for an Oscar. Dennis Lehane, chronicler of America's dark underbelly, adapted it from his own short story, Animal Rescue.
Hardy stars as the impassive, taciturn barman of a dive bar in Brooklyn who rescues an abused puppy from the fragile Nadia's (actress of the moment Noomi Rapace) rubbish bin, where it was dumped by her thuggish ex (Matthias Schoenaerts). The film also features James Gandolfini in his final role as the bar's beaten-down owner, who's in over his head with the Chechen mafia. "James was a great actor, a great artist and such a beautiful guy," says Hardy.
As a tightly wound saga of gangsters, have-nots and life's wounded strays healing each other, The Drop has the sting of over-familiarity. But Hardy is mesmerising; with none of the bombast he brought to his Batman villain Bane or Bronson, the actor steers a course of quiet, restrained magnetism, until the trigger is inevitably pressed and the violence within unleashed. Of course they wanted Hardy for bartender Bob (whose nickname should have been "Silent", an honorary twin to the small-time crook "Handsome Bob" Hardy played in Guy Ritchie's RocknRolla).
Hardy signed up for The Drop after his good friend Rapace had scouted the script, met Roskam in Brussels and excitedly Skyped Hardy while he was shooting George Miller's Mad Max sequel in Namibia to enthuse about the European sensibility the director would bring to this working-class American noir.
Hardy says, half-jokingly, "I like dogs, I like New York and I like characters that are desperate and lonely and aren't normally looked at under the microscope. Hustlers and pimps and villains and drunks and homeless people and loneliness; disparity and the losers."
With Bob, Hardy set out to explore "the layers of denial and the masks that you have to create in order to participate in life, on life's terms, whilst trying to deal with having done something so heinous that you can't forgive yourself, but at the same time you can justify. The complexity of that I found fascinating; that was a big challenge in its own right."
Interestingly, Hardy admits to missing a crucial element of Lehane's script which had huge repercussions on his character's motives and actions and directly relates to the "heinous something" he mentions. Without revealing what it is, it acts as the linchpin for everything Bob does during The Drop's climactic stretch, and I confess to Hardy that it boggles my mind that he missed it in the script - which he surely must have read several times while preparing? "It was a big miss," the actor says. He's laughing now, not in a flippant "silly me!" or sheepish fashion but because he finds the blunder genuinely funny.
"I like to think I'm confident and pretty good at what I'm doing - and I missed that key thing! Three weeks into the shoot, Noomi turns to me and says: 'You do realise what's in Bob's basement?' I said: 'That's a very good point, Noomi. Why is it in my basement?' And Noomi says: 'I love the way you're living Bob, because he would shut it out, too.' I was like: 'No Noomi, I just didn't read the script properly'."

Hardy's merriment reaches a crescendo. It's reassuring to hear a big-time actor own up to a mistake, and you never would have been able to see that anything was amiss with his performance in the final film. Although, had Rapace not alerted him, it makes you wonder.
Hardy describes himself and the Swedish actress, who's making her own strides across the American movie landscape, as "kindred spirits". The pair met on a project that never came to fruition but decided to scout hard to find something else instead, although Rapace did the heavy lifting.
"It's all about teams of people," says Hardy, who's also due to appear opposite Rapace in the Stalin-era thriller Child 44. "No one auditions at the top level. It's a conversation with a director or other actors as people discuss a project that's in the ether. And Noomi is awesome at finding stuff. She's ahead of the game; she knows everything about everyone, whereas I'm not so good at that. I do sitting down and waiting."
"If I don't know who a director is," he continues. "I'll text Noomi and go, 'who's this dude?'
"'Oh, he directed The Godfather.'
"'What's that about?'
"So, I'm a prick. But getting me in the room with a director is key because I'm not a great reader or watcher of films."
Born in Hammersmith, Hardy, who first came to prominence when he was cast as the villain in 2002's Star Trek: Nemesis, is way past the stage where he has to beg directors to cast him. "I've done that. It doesn't get you anywhere good and leaves a bitter taste in your mouth."
Those post-Star Trek years were the most difficult ones he faced, professionally speaking. That near miss at stardom left him resentful that his big break hadn't transformed immediately into a glorious career, but that was partly because of the personal troubles that followed him out of his wayward youth. It was about this time that Hardy's addictions to booze and crack cocaine spiralled out of control. He once said, "I would have sold my mother for a rock of crack," but he conquered both addictions with rehab and cognitive therapy. He has been sober for over a decade and married his long-time girlfriend, the actress Charlotte Riley (they met as co-stars on the series The Take and Wuthering Heights) this year.
His lack of awareness about film-makers or people to know in the industry has had no adverse impact on his career. Assuming the role of Max Rockatansky from Mel Gibson in Miller's post-apocalyptic franchise is a big building block for Hardy's international profile.
Following his solo car journey for writer-director Steven Knight in Locke, he is starring in the second series of Peaky Blinders (season one is currently screening here). He has also filmed biopic, Legend, of the East End gangsters, Reggie and Ronnie Kray (in which Kiwi actor Jacob Tomuri is his stunt double).
Despite his concerns about not having enough time to be with his son, Hardy is driven by work. He can't stop because the offers won't stop. "If you're on something, once you've done it, you move straight on to the next one," he says. "But I see it all as a big school. What we do in many ways is a university of a type, metaphorically speaking, and I have the opportunity to study people and life through my work. I open up doors to experiences that I wouldn't have if my job wasn't this, and I get to visit lots of places, in extremis."
Back when we spoke in Soho, with Peanut by our side, Hardy told me he'd made a conscious decision to sculpt himself into a musclebound athlete "to establish myself as someone you would take notice of and further my employment". It worked wonders, sending Hardy's career skyward and giving him options he'd never dreamed of.
As long as he can continue channelling what he refers to as "dysfunctional, erratic personality-disorder characters" and prowl the recesses of damaged, lonely, tormented minds, he'll be around for a very long time. "You have to try everything and it's all a process of elimination," Hardy says of finding his way through the dark days to today. "But ultimately you find your path."
The Drop is in cinemas now. Child 44 and Mad Max: Fury Road will be released in 2015.
