In addition to his work on So Awkward, Archie also provided his voice to the video game Final Fantasy XIV: Heavensward and played a younger version of Jack Whitehall's character in the BBC comedy Bad Education.

Whitehall mourned his late costar in a tribute on Instagram, writing that he had met Archie "nearly ten years ago" when he first cast the actor in a short film he wrote. The comedian went on to work with Archie in a comedy special before recruiting him for Bad Education.

"Every time I worked with Archie he was the same - passionate, generous and pitch perfect, he was loved by everyone on set," Whitehall recalled. "I have no doubt he would have had a long and illustrious career and would have continued lighting up the lives of all those who encountered him."

"The world has been robbed of a truly special soul," he continued. "He will never be forgotten, i feel utterly devastated that he is gone but i also feel so blessed to have met him."

Archie's So Awkward castmates also paid tribute to the star on social media.

“Archie, I can’t even believe I am writing this. It’s taken me a while to be able to find things to say as I am at an absolute loss for words. You were the most beautiful soul I have ever known, the most unique, loving and caring person on this planet,” Cleo Demetriou wrote, alongside photos of the pair.

“My heart is completely broken knowing I that I can never see you again, never speak to you again and never hug you again," Demetriou added. "Thank you so much for being you, an absolute light in this sometimes very dark world."

Game of Thrones actor Samuel Small shared photos and videos of himself and Archie through the years, writing on his Instagram, "To my brother Archie. I still can’t quite comprehend that you have passed. You still had so much life to live and I’d give anything for you to keep on living it."

"My heart aches all day and everyday thinking about you and I just wish I could talk to you just one more time so you could know how much I loved you. I vow to make you proud with every last breath," Small continued. "Archie was there for me in my lowest lows but my highest highs were with him. Archie’s my best friend and to say goodbye so soon is absolutely devastating, but his calling was obviously somewhere else and I hope he is brightening up wherever he is."
