Her father’s Scottish brogue is part of his trademark appeal. 

However, his decision to move to Los Angeles decades ago as his career took off led to his daughters developing a distinct American twang.

Now, McGregor’s daughter Clara has shared a family video she says captures the last time she and her sisters had ‘British accents’.

At the time the video was filmed the girls had been living in London, which had been their home since they were tots.

The sweet clip shows a young Ms McGregor leading her pyjama-clad siblings in ballet exercises while her sister Esther exclaims ‘oh yes, I’m listening!’

One after another, the girls then wish their dad goodnight in distinctly English accents that are a world away from their current Californian drawls.

Sharing the post with her 130k followers, the model and producer joked that the footage is a relic of ‘the good old days’ before her family relocated to Los Angeles when she was a teenager.

The girls were born in London, but international demand for their father’s Scottish charm soon took a toll on their own accents as McGregor’s filming schedule drew the family across the globe.

The sisters spent three years living in Australia while their father filmed the Stars Wars films and Moulin Rouge, then moved permanently to the States in 2008.

These days Ms McGregor lives in New York, where she studied photography and is currently forging her an acting career of her own.

While the 28-year-old is proud of her transformation over the years, her father has previously faced criticism for abandoning his British roots.

‘There’s a sense you’re turning your back. People in Scotland to this day tell me to remember where I come from,’ he told Radio Times.

He added: ‘I don’t need anybody to remind me. It’s this feeling of you’re not Scottish enough. I’m Scottish wherever I am in the world.’

In a bid to reconnect to his native country, the actor returned to Scotland in 2023, accompanied by his second wife Mary Elizabeth Winstead.

The pair purchased a £2million home in rural Perthshire, which they spent the past year lovingly restoring.

During an interview at Comic Con exhibition in Edinburgh last year, the Trainspotting star explained that he had made the move after struggling to shake off the memories of his beloved homeland.

He said: ‘I miss the landscape. I miss the air in Scotland. I miss the smell of the rain, the smell of the green and the colours of Scotland. 

'And the people and the culture. I could just keep going on and on.’
