He may be best known for his stint on 'Made in Chelsea' and more recently, for his marriage to (and podcast with) Vogue Williams - but Spencer Matthews has a new and very personal project on the horizon.

In 1999, when the Londoner was 10, his older brother Michael died on his ascent from Mount Everest, having reached the summit of the mountain three hours earlier.

The 22-year-old's body was never recovered and it is something that has understandably caused a great deal of anguish to the Matthews family over the years. He was the 162nd person to die on Everest.

Now, however, Spencer has returned to Nepal in a bid to retrace his late brother's footsteps and attempt to find his body - and it's all been filmed for a new documentary, 'Finding Michael', which will premiere on Disney+ in February 2023.

Matthews told Holly Rubenstein's 'Travel Diaries' podcast: "I was aching to find out more about his death. I was ten at the time. I remember thinking it was really unfair. 

"I always believed that I’d see him again and never took it on the chin that he was dead. I thought it was impossible. It never crushed me in the way it affected my parents and my brother."

His other older brother, James, is married to Pippa (sister of Kate) Middleton.

He added that he had undergone 'months' of therapy in preparation for the trip, saying: "It was important for me to get my head around the fact I might come face to face with my brother’s frozen body. I knew it was going to be a gut-wrenching and emotional journey."

"I’ve always been uncomfortable with him being up there, especially in plain sight," he said. "Around 600 people a year summit Everest. I’ve always been uncomfortable that he could be laying up there like some kind of tourist attraction but also on his own, away from us. 

"He died up there and his last thoughts will probably have been that he’s never going to see his family again. We have not seen his body and I set off to go to Everest and find him and bring him home. We made a film about it. It’s called Finding Michael and it’s out in February 2023."

Spencer travelled to Nepal earlier this year, just five days after wife Vogue gave birth to their youngest son, Otto, due to a limited window of ideal weather conditions opening up for the trip. Otherwise, the project would have been delayed by a year.

"Part of the film is that we retrace the exact steps that Mike and his friends took," he said. "We stay in the same places and do the same path as he did. It’ll be a really powerful and amazing film."

At the time of his death, Michael was the youngest Briton to have scaled Everest at just 22 years old.
