However, it’s not always been smooth sailing for the 33-year-old actor.
The actor has opened up about his battle with addiction and his journey to sobriety.
He tweeted: “12 and a half years ago I was in active addiction.
"Hurting myself and those around me who I loved the most. It got so bad that eventually I ended up in a hospital for mental health. I am now 7 1/2 years clean and sober. I have made many mistakes in my life.”
Twelve and a half years ago was just after he starred in the Twilight movie New Moon and just before his debut in the Harry Potter film series.
Campbell Bower also took the opportunity to give a few pearls of wisdom to those struggling with addiction currently.
He wrote: “But each day is a chance to start again. Atone for mistakes and grow.
“For anyone who wakes up thinking “oh god not again” I promise you there’s a way. I’m so grateful to be where I am, I’m so grateful to be sober. I’m so grateful to be. Remember, we are all works in progress."
The Twilight actor has previously opened up about his struggles with drugs and alcohol.
He told i-D in 2019 that being honest with himself was essential to his recovery process.
He said: “I’m in recovery, so one of the first things that they teach you when you’re in recovery is to be super honest about what it is that you’re feeling, like guilt, shame, fear, sadness, whatever it is.
“The most important thing is, and it’s the hardest thing to do, is just express exactly what it is that you’re feeling.”
The actor took a few years off from acting to travel abroad touring with his London-based band, Counterfeit, for which he provides the lead vocals for.
However, he’s made quite the comeback recently, with many praising his performance in the latest season of Stranger Things.
He's also become a viral sensation with interview clips and Vecna memes circulating the internet.
Campbell Bower recently opened up to Vanity Fair about seeing himself plastered all over social media and said: “It’s fine. It’s lovely. You can’t stop the internet.
"The internet is a hive mind in and of itself, so you just have to release control at a certain point and just go, ‘Do what you need to do. You’ll calm down in a minute’”.Featured Image Credit: REUTERS / Toby Melville / Alamy Stock Photo. Netflix
