Joseph Quinn, who is popularly known for his role in the Netflix series "Stranger Things," couldn't control his tears when a fan praised him during the Q&A session held at ComicCon on Saturday.

The video of Quinn breaking down in tears was shared Tuesday on YouTube, where the fan can be heard talking about how poorly he was treated by the organizers and yet he managed to take time for fans and made their summer special.

"Mine’s not really a question, it’s just more of an extension of gratitude really," the fan said in the video. "I’m sure a lot of us have heard what happened [at the meet-and-greet], whether it’s true or not, about how you were treated… But I just wanted to say thank you from all of us."

The fan added, "We’re really grateful that you’re sharing your time, thank you for signing our things, for spending time with us and making our summer."

The crowd began to cheer and applaud the actor as he wiped his tears.

Following the London Film and ComicCon event held in London, many fans took to Twitter to share how the organizers treated the actor badly.

One of the fans wrote a tweet, "The organisation was a shambles and the staff were rude as hell. But Joseph Quinn was so genuine and friendly and gave me a hug even though the staff were yelling at him to hurry up. Top bloke."

The fan also shared a photo of the actor hugging him Monday.

Another fan shared their experience in a separate tweet, "The way LFCC treated Joseph Quinn was horrendous, I feel so bad for him. Both Joe and the fans were treated like shit all for LFCC to make as much money as possible."

"LFCC really need to treat the guests with respect. And the ‘staff’ constantly shouting at you," the fan added. Many more fans shared similar experiences on Twitter.

Quinn played Eddie Munson's character in the popular TV series, "Stranger Things." He will be next seen in a drama movie, "Hoard," which is currently under post-production. The 29-year-old actor will play Michael's character in the movie and the flick is helmed by director Luna Carmoon.
