The 25-year-old actor's dad died when he was 18 and filming the TV show 'Skins' and Jack revealed that when he was starred in Angelina Jolie's 2014 movie 'Unbroken', her husband Brad Pitt sympathised with him and insisted he was around if Jack ever needed to talk.

He said: "It was tough - I lost my dad halfway through [filming 'Skins']. I'm trying to do a comedy drama and I've lost one of the biggest inspirations of my life.

"Brad was like, 'Look man, I know your situation and I know you lost your dad. Just to let you know I'm here if anything's puzzling you.'"

Jack also praised Angelina, 40, for being incredibly down to earth and reminisced about when he took her to his local pub in Derby.

He said: "She wanted to meet my people. We all went to this place out of the way in Derbyshire, a pub where you can eat nice food. She came up on her own, man. She has some security people but they weren't really involved and, yeah, we were all just sat around."

However, despite his praise for Angelina and Brad, he admitted that he still hasn't fully recovered from his dramatic physical transformation for 'Unbroken', where he lost two stone.

He explained to ES magazine: "I think I damaged myself, man. I feel like my kidneys are a bit f***ed up. The thing is, I don't want to bad-mouth anyone, but... getting to a point where you're ready for the film, they'll help you with all day long. Getting yourself back to normal again, that's considered your responsibility."

Jack also opened up about managing to escape jail time for a violent crime which he won't elaborate on and how his suspended sentence made getting an American visa difficult, even losing out on a major film role because of visa issues related to the incident.

He said: "It was all stacked against me... I'm not going to make out that I sailed through it all feeling very cocky and sure-fire, like. I was f***ing terrified. But that was because of what I was potentially gonna lose. It was a case of putting a good version of accounts over to the court - for them to say, 'Well, there's a chance he might make something for himself if we don't send him down this time.' Thankfully they gave me a suspended sentence."

"It's been hard enough trying to get into America with all of that said and done. So I can't imagine, if that conviction had amounted to anything, how different things would be."
