Spencer Matthews and his mother attend premiere of documentary Finding Michael

Spencer Matthews and his mother were reunited at the premiere of the Made In Chelsea star’s new documentary film: Finding Michael.

The film, commissioned by Disney+, details the emotional story of Matthews’ attempt to retrace the steps of his older brother Michael – who disappeared on Mount Everest in 1999.

Michael Matthews became the youngest Briton to summit Everest at the age of 22, but disappeared on the mountain just three hours later.

23 years on, Finding Michael shows Matthews’ journey to follow in his brother’s footsteps in an attempt to find him and bring his body home.

Heading up the expedition team is Nirmal ‘Nims’ Purja – the world record holder for climbing all 14 mountains over 8,000 metres the fastest.

The pair face unexpected and extreme challenges as well as intense time pressures when the weather closes in, during their expedition.
