He's unrecognisable these days

Jimmy Karz played the young student in the Danny DeVito adaptation of Roald Dahl's famous book, but he's long since been doing something else with his time other than acting.

After starring in the iconic scene in the movie, Karz landed a role in The Wedding Singer a couple of years later, along with playing a part in an episode of ER.

And it seems the hospital drama had a lasting effect on him because he went back to school to study medicine shortly after it.

After working as a teacher for struggling communities, where Karz helped them grow their own food, he decided to enrol at the Philadelphia College of Osteopathic Medicine.

"Through gardening, I learned a little bit about biology and chemistry, enough to realise I wanted to delve more into science," he said back in 2015.

"I went back to school to study biochemistry, which led me to medicine. I liked osteopathic medicine’s focus on helping the whole patient, and I was interested in learning manual techniques to help patients."

As for how they filmed his iconic scene, Matilda director Danny DeVito revealed it took two weeks to complete with Karz and Ferris staying behind after the day's shooting had wrapped up to film it.

DeVito said it was a disgusting scene to shoot, especially as Karz was not allowed to swallow the cake he was eating and had to spit it all out between takes.

As the director he also had to remind crew members not to wipe the actor's mouth between takes, while Karz remembered that he had to wear the same outfit for the scenes and it became encrusted with chocolate.

Unsurprisingly, he wanted nothing to do with chocolate for a few weeks after finally finishing the scene.

But they cake did make a reappearance a few years later when the cast reassembled to film this:
