He studied at the University of North Carolina on a basketball scholarship before enjoying a professional career in Spain, China, Italy, Greece and England.

He then turned his hand to acting, also playing the villain The Fisher King in BBC’s Doctor Who in 2015.

He was born weighing 14lbs and reached 7ft by age 11.

Speaking in 2007, Mr Fingleton said: ‘I do cause a bit of a stir wherever I go, with people pulling out cameras, but it doesn’t bother me.’

‘I’ve never been embarrassed about my height and I actually like the size I am. It’s something unique and original.

‘My group of friends are great and I come from a good family, so being tall hasn’t ever been an issue. I’ve not been self-conscious.’

He told the Guinness World Records when he was confirmed as the tallest man in Britain: ‘My great grandfather was 6ft8in. I have always been taller than everyone since I can remember. My height really took off when I reached 11 and was touching 7 foot. By the time I was 16 I was 7ft5in and stopping growing at 18 when I was 7ft7.56’.

‘I have never been self conscious about my height. I am more conscious of going fat and bald so that should tell you. I never let my height play a negative part in my life.

‘I always do what I want, some tall people may be restricted as they are constantly stared at or people ask the same questions over and over. This is the only bad thing about being tall – the stupid remarks and questions. Other than that, being tall is great.’

‘I have been doing acting work since my basketball career finished. I spent 8 years in the USA attending High School and College. I graduated from the College of the Holy Cross in 2004 with a degree in History.

‘I have played professionally in Greece, Italy, Spain. Now I am concentrating on acting and trying to move to LA soon to jump in with both feet so to speak.’
