Soon the queue was getting longer and my enthusiasm was becoming less controllable. When it became so long that we couldn't see the end of it from where we were standing, it moved! Now, my excitement turned into nerves.
Amidst all this, everyone was looking for film stars. Finally, we heard screams and giggles: someone must have arrived. Then we saw the only celebrity there... Newsround's Lizo! He greeted fans and then moved on.
I was at the front now. In my head, I practised my drama piece and what I was going to say. I grasped at my CV and photos, anxiously. This was it. I thought to myself, 'What if I don't get it? I'll be so disappointed... but what if I do get it?'
I was nervous and excited, each making the other worse... I really wanted this. Not just because it was HP but because I want to be an actress. I wanted to seize every opportunity I had.
The fact that it was HP made me want it even more. I needed to know that if I failed, it wasn't through lack of effort.
I followed a casting director into the studios, leaving my mum outside. The audition was different to what I'd expected.
The casting directors thanked us for coming. We filled in forms and then they took our photos. They said if they wanted to see us again, they'd contact us. And it was over!
It was a brilliant experience, so thank you, Livi, for telling me about it, and Ellie and Holly for helping me prepare. Obviously thank you mum for taking me. And thank you Newsround for letting me share my first taste of 'showbiz'!"
