13-year-old Dubliner Alisha Weir told Ryan Tubridy on Friday's Late Late Show about landing the lead role opposite Emma Thompson in the upcoming movie version of Roald Dahl's Matilda The Musical.

The young performer is heading for international stardom, playing the eponymous Matilda in a tale about a courageous young girl who defies both her uncaring parents and a terrifying school principal.

But first Ryan asked about her performing on The Late Late Toy Show. "It was 2017," she told him. "I can look at myself on Youtube . . . and it’s a really good memory to look back on.

"I look quite different as I have no teeth in," she added, which drew a laugh from the audience. "I really enjoyed it, being with all the kids and the buzz. And because it’s around Christmas time and I’m happy."

After playing a clip of her singing Cyndi Lauper’s True Colours, Ryan moved on to her role in Matilda The Musical. "How do you think you got it?" he asked. "What happened?"

"To be honest, I’m not really sure how I got it," she told him, "because there was so many incredible people that must have auditioned. So really I have no idea, but I’m just really grateful for the opportunity . . .

"And even when I was working with all the kids, they were all so talented at singing, at dancing.

"So I’ve absolutely no clue how I got it - but I’m just really grateful that I did get it."

Ryan also asked her about starring alongside Emma Thompson, who plays the baddie Miss Trunchbull in the film, an adaptation of the musical based on Roald Dahl’s much-loved story.

"I watched her in all these films when I was growing up. To be in my first ever big film with her is really crazy," Alisha admitted.

"She’s just really, really kind. I was looking up to her as well because she’s done loads of these [films] and this was my first ever time, so I was learning off her.

"And I think that when she was filming it was like two completely different people.

"There was Emma Thompson and there was Miss Trunchbull - so when they said 'Action’ she just switched into the character. And when they said ‘Cut’ she’d switch back to Emma."
