My Mum called me and she said, Louis, you have to do this audition.

It was that day.

I thought, I dont really know anything about it and chances are I might not get it.

But then I thought, Oh no, Ishoulddo it, because its a big audition.

I went into the screen test wearing my school sports kit.

Our casting director saw thousands and thousands of kids.

He turned up in his rugby kit, looking a bit annoyed and grumpy.

He sort of blew everybody out of the water, did an amazing read.

Then I think the next day he found out that Id doneAttack the Block, which he really liked.

Then he read the script and then he was in.

And he turns out to be an absolutely fantastic kid.
