Isaac Hempstead Wright wants to start a band with his 'Game of Thrones' castmates.

The 17-year-old actor - who portrays Bran Stark in the fantasy drama series - thinks it would be ''cool'' to team up with his co-stars and make music together, though he thinks there could be some rows about the sort of material they would produce because they all have different tastes.

He said: ''We've got Natalia Tena (Meera Reed), who has a band. Thomas Brodie-Sangster (Jojen Reed) is in a band, and he plays guitar.

''We've got Jacob Anderson, Grey Worm, who's a rap artist. We've got DJs, too.

''Kristian Nairn (who played Hodor), of course, is a top-notch DJ, and he used to play the organ. So it's quite nice.

''We used to joke that Bran and Hodor should start their own musical troupe, so how cool would it be if we formed a 'Game of Thrones' band?

''We need to get together and jam. Hodor and Bran and Jojen and Meera jamming along with Coldplay. That would be insane!

''The thing is, we're all from very different musical backgrounds, so there might be some in-fighting there.''

However, Isaac - who plays piano - admits the thought of getting on stage is terrifying because he suffers from stagefright.

He told Vulture: ''I do get terrible stage fright. I've been playing piano since I was eight or nine, but I hated it to begin with. My mom forced me to play it, and I was close to giving up, close to saying, 'Stop making me do this. I hate it,' and eventually it just clicked and I loved it, and it was my favourite thing in the world.

''I remember one occasion at school, playing a piece, and I was literally halfway through it, it was going really well, but then I messed it up a bit, and I just froze.

''It was one of the most mortifying moments I've ever had! And so I'm always quite anxious about performing in public.''
