Fans were left stunned after spotting Owen Cooper’s drastic growth spurt in the two months since Adolescence hit our television screens.

The cast of the hit Netflix production jetted off to Los Angeles earlier this week for a screening of the show as they step up their preparation for the Emmys.

At the age of just 15, Owen is favourite for the Best Supporting Actor award for his incredible performance as troubled teenager Jamie Miller.

If successful, the sensation would be the youngest ever male winner in the 76-year-old history of the ‘TV Oscars’.

But after Owen flew to California, eagle-eyed fans of the series were shocked to see how much he’s grown in just a matter of months.

Fans were left stunned by Owen Cooper’s drastic growth spurt after the cast of Adolescence jetted off to Los Angeles earlier this week

The 15-year-old acting sensation looks year older than he did after the show’s release in March

Posing at the premiere of Adolescence in central London just two months ago in March, Warrington-born Owen was noticeably smaller than co-star Ashley Walters (pictured L-R: Cooper, Ashley Walters, Robbie O’Neill, Hannah Walters and Stephen Graham)

The 15-year-old now towers over the show’s writer and onscreen dad Stephen Graham despite being noticeably smaller than his co-star at a premiere in London in March. 

Looking dapper in a pair of black suit trousers and a navy and black jacket, Owen posed for pH๏τos alongside the 51-year-old, who is five-foot-five, at Wednesday’s event.

The young star, who looked considerably older with a longer haircut, is also well and truly gaining on Ashley Walters, 42, who stands at five-foot-nine. 

The three men of the moment seemed pleased to be stepping out together as they stopped for pH๏τos alongside fellow co-star Erin Doherty, who looked effortlessly stylish for the appearance in a shirt suit and a co-ordinated tie. 

Cooper had flown to Los Angeles having watched his beloved Liverpool lift the Premier League trophy at Anfield on Sunday. The Adolescence star, who is still in school, jetted off after the beginning of the English half-term. 

Having originally been touted for the Best Actor award, Owen is now to be nominated for Best Supporting Actor at the Emmys.

Experts hailed the ‘genius move’ not to enter the Warrington-born star into the Best Actor category as it significantly boosts his chances of winning. 

Despite experts calling Owen a ‘lock-in’ for the award, the modest teenager appeared to be taking the adulation in his stride, saying he would ‘just take it and move on’ if he bagged the gong. 

Just a couple of months later, Owen is towering over writer Stephen Graham and well and truly gaining on Ashley Walters, who stands at five-foot-nine

The Brit’s main compeтιтion in his category is Javier Bardem, who starred in Monsters: The Lyle and Erik Menendez Story and was initially the bookies’ favourite.

Speaking to Gold Derby last month about the prospect of gaining recognition with awards, Owen said: ‘If that was to be the case, it’s definitely a mᴀssive achievement and it’s the next step in my life. I’ll just take it and move on.

‘It’s one of them things that will forever be there and I’ll never forget it for the rest of my life.’  

And he deflected the praise back to the team who surrounded him on the show.

‘It’s all rooted from Stephen [Graham], Hannah [Walters, the producer], Phil [Barantini, the director], Jo Johnson the producer, it’s all from them. I couldn’t have done it without them,’ he said. 

Cooper, who hails from a proudly working class estate in central Warrington, was chosen from 500 candidates for the role of Jamie. It was his first-ever acting job and no one in his family has a background in the industry.

He is being supported on his meteoric rise by dad Andy, an IT worker, and mum Noreen, a carer. Speaking about the change in their lives, Noreen said: ‘It’s such a shock, but we’re getting on with it.’

Owen’s performance in Adolescence captured the attention of the world

The 15-year-old has been described as a ‘shoe-in’ for the Best Supporting Actor award at this years Emmys

Brand and culture expert Nick Ede predicted Owen could follow in Timothée Chalamet’s footsteps and become ‘the toast of Hollywood’.

He told MailOnline: ‘The phenomenal success of Adolescence has taken the TV world by storm and critics have been raving about Owen’s stand-out performance. 

‘The Hollywood elite love a rags-to-riches story and, at 15 and his first ever role, this young actor who was brought up in humble surroundings could soon become Hollywood’s H๏τtest property and follow the path of many other child stars who have become household names, like Millie Bobby Brown or Timothee Chalamet.

‘I’m sure writers will already be presenting his agents with scripts and synopsis that will feature him.

‘As he’s so young I am sure he will be looked after and not thrust into the limelight without any support.

‘Being a star in the UK is very different from being an international phenomenon. I am sure the offers will be rolling in from feature films to brand deals and beyond.

‘He will probably feel a lot of pressure, but also feel a mᴀssive sense of achievement from where he has come from to where he is now.’

The Emmy award ceremony is expected to take place in LA in September.
