Rupert Grint finds it very hard to ''separate'' himself from Ron Weasley.

The 28-year-old actor shot to fame playing the young wizard in the eight-film 'Harry Potter' series and though it is almost six years since the final movie was released, he still feels attached to the character and thinks it will always be a part of him.

He said: ''I think it's always going to be a challenge [to move away from 'Potter']. They're so widely liked and watched and new generations are coming into it, so it'll always be there.

''It's never really been a conscious decision, I didn't really go out to pick shocking, very adult roles. I'm driven by scripts and people around me. But yeah, you do want to try and step away from the comfort zone...

''I think [Ron] will always be with me. I had a weird relationship with that character because after that we kind of merged into the same person.

''I find it very hard to separate where I end and Ron begins.''

And Rupert can understand why he feels so tangled up with Ron because shooting the movie series largely took place through his formative teenage years.

He told the Vulture TV Podcast: ''We went through quite an important time in our development, I think. And naturally we just merged into the same thing. It's quite strange growing out of it.''

The 'Snatch' actor recently saw the West End play Harry Potter and the Cursed Child' - which is set 19 years after J.K. Rowling's final novel, 'Harry Potter and the Deathly Hallows' - and found it ''weird'' to see someone else portraying Ron.

He said: ''I saw the play, 'Harry Potter and the Cursed Child'. It was very strange.. because you're watching an older version of yourself.

''It's a character that I feel is part of me. It was almost like an out-of-body experience.

''But yeah, it was incredible seeing it move on, and seeing someone else's interpretation of it as well was really interesting. I really enjoyed it.''
