Robert Aramayo has been hailed an inspiration by people in his home city of Hull following the actor's Bafta success.
As well as being named best actor for his portrayal of John Davidson in the film I Swear, Aramayo also received the Rising Star award.
The actor, who studied performing arts at Wyke College in the city and attended Hull Truck Theatre, broke down in tears on stage and said afterwards: "It totally blows my mind."
Laura Bulles, from the college, said: "It felt like the whole of Hull was behind him to get that newcomer award and then to get leading actor, it's just absolutely phenomenal."
Bulles added: "It's an amazing thing to happen for a lad from Hull and for our students to see.
"That is just something they can take with them now on whatever they are going to do next."
In an interview with BBC Radio Humberside in October, Aramayo spoke about being "lucky enough" to be involved with Hull Truck Theatre during his early career.
Commenting on his achievement, the theatre's artistic director, Mark Babych, described it as a "jump up and down" moment.
"What an incredible result," he said.
However, he said he was not surprised as "Rob is a phenomenal actor", adding the recognition was also great for "theatres like ours" and the role they play in encouraging young talent.
"We are just incredibly proud of Rob, who is clearly an enormous inspiration to people," he added.
Babych said Aramayo had also demonstrated "a great deal of authenticity, respectfulness and insightfulness" in tackling the role.
Tourette's syndrome is an incurable condition that causes someone to make sudden, repetitive sounds or movements, known as tics.
I Swear follows Davidson's struggle growing up with Tourette's in 1980s Scotland.
Davidson was made an MBE in 2019 for his efforts to increase understanding of the condition and help families deal with it.
Aramayo described Davidson as "the most remarkable man I have ever met".
One of the film's producers, Georgia Bayliff, said she was also "incredibly proud" of Aramayo, and how hard he had worked on the role.
"There were so many heavyweights in that category - new and old - but we knew what the performance was like seeing him every day on set," she said.
"It was wonderful our peers recognised that."
She also praised everyone involved in the production, adding its success was due to it being "a personal story that could resonate on a global scale".
