He appeared in several follow-up documentaries as he grew up, and his story has been adapted into the film I Swear.
Robert Aramayo stars as Davidson and won Best Actor at the BAFTAs last night, beating out Timothée Chalamet, Leonardo DiCaprio, Ethan Hawke and Michael B Jordan.
Davidson went on to be honoured with an MBE in 2019, and due to his nerves exacerbating his tics, he swore in front of the late Queen Elizabeth II.
He told the BBC: « I began ticcing and shouting and I was absolutely mortified.
« But then I felt a hand on my shoulder. It was one of the Royal Archers, the Queen’s bodyguards while she’s in Holyrood, and a voice said ‘Don’t stress, she knows all about your condition’.
« That to me was huge because I’ve struggled so much with everyday life, with people misunderstanding, and if the Queen of the United Kingdom can understand and ignore the tics and the swear words then why can’t the rest of society? »
The 83rd annual Golden Globes was full of drama, including many borderline jokes made by host Glaser.
The 41-year-old comedian took aim at Leonardo DiCaprio and his history of dating younger women, as well as making a shocking joke about Jeffrey Epstein.
Glaser also turned her attention to Jordan during her opening monologue, where she discussed the actor playing twin characters Smoke and Stack in last year’s horror, Sinners.
The host jokingly said: « I can’t believe it, we got two Michael B. Jordans. When I saw that, I was like, Nikki B. Jerkin’, because that was awesome. »
