"Sadly it has come to our attention that Neil Fingleton Britain's Tallest man passed away on Saturday," wrote Facebook group The Tall Persons Club. "Neil started off in basketball in the USA before becoming a actor and starring in the X-men first class and also recently in the Game of Thrones. Our thoughts and condolences go out to his family."
Fingleton, who was born weighing 14 pounds, described himself as a "happy go lucky guy." He once said his height didn't bother him, and said he's heard the joke "what's the weather like up there?" a million times.
"I do cause a bit of a stir wherever I go, with people pulling out cameras, but it doesn't bother me," Fingleton said during a 2007 interview with a local Durham newspaper, NME reported. "I've never been embarrassed about my height and I actually like the size I am. It's something unique and original."
He said friends and family had never made an issue of his height and that he was not self-conscious.
Fingleton was confirmed as Britain's tallest man in 2007. He was also confirmed as being among the tallest 25 men in the world. He issued a statement on the Guinness World Records website that year:
I am one of three siblings -- my sister who is 6ft3in is the eldest at 30, my brother is 6ft8in who is 29 and I am 7ft7in at 26... my mother is 6ft and my father was also.
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.
