HARRY Potter actress Bonnie Wright appeared on This Morning today as an expert - 21 years after first appearing in the hit films.
The star first appeared aged nine in Harry Potter and the Philosopher's Stone and went on to star in the next seven movies.
Bonnie played Ron's little sister Ginny, the youngest sibling in the Weasley family.
As Potter fans will know, Ginny becomes Harry's main love interest in JK Rowling's story and - spoiler alert - marries him at the end of the series.
Since finding fame in the films she graduated from university in London, then founded a production company and began making short films.
She has also directed music videos, including one for Scarlett Johansson's song Iguana Bird with Pete Yorn.

These days she is also known as an environmental activist and appeared on the show to talk about how to be sustainable.
If she was hoping hosts Dermot O'Leary and Alison Hammond didn't mention her Harry Potter past, she would have been disappointed.
Alison said: "Actress Bonnie Wright has taken a little bit of a break from spells to talk to us about sustainability and what we can do to help the planet.
"Can you believe it's been like 20 years since that scene?"

She replied: "I know, it's scary. Time flies. I didn't know I had a line until that day. They gave me that 'good luck' line."
An onscreen caption shown while she was on air made a nod to a Harry Potter-esque spell, reading: "Eco-spelliarmus!"
Bonnie also spoke about her book of eco tips, Go Gently: Actionable Steps To Nurture Yourself and the Planet, which came out last month.
