Harry Potter star Matthew Lewis, who played Neville Longbottom, explained how he thinks the film's young cast avoided the “pitfalls of being a child actor.”

“I've been asked before about the pitfalls of being a child actor, and we seem to have avoided them. 'Every so often, I hear people say that they were the only actor in the film and had to carry the film on their own and all of the pressures and anxieties that come with that. We, on the other hand, were all in it together.”

He went on to say that “a lot of the fears we had were all shared” and that “no one but each other could understand exactly what we went through and how it affected our personal lives.”

Lewis played a Hogwarts student alongside Daniel Radcliffe, Emma Watson, Rupert Grint, Tom Felton, and many other young people.

Thirteen years after the premiere of the final Harry Potter film, what is most important to Lewis are the friendships he made along the way.

“One of the things I hold on to is that friendship,” he said. 'I never go back to the book. The only thing I still hold on to are the relationships I built through that film.”

Childhood stardom has received a lot of attention recently, with many former child stars talking about how their lives suffered as a result of their childhood fame.

The latest example of this is by Demi Lovato, who recently released a documentary, Child Star, in which celebrities such as Raven Symone, Drew Barrymore, and Kenan Thompson tell their stories.

The film has inspired Lovato to advocate for “protections” for young people in the entertainment industry so that future generations will not experience what she and other stars of film have experienced.
