“Watching Michael J. Fox hug Christopher Lloyd like this is so beautiful,” wrote one Twitter user. “I think it’s safe to say that today belongs to Michael J. Fox and Christopher Lloyd. As it should… It’s a beautiful moment in time.”

Fox was diagnosed with Parkinson’s disease in the 1990s, and he told the NYFCC audience that Lloyd has always been there supporting him over the years.

“Parkinson’s is the gift that keeps on taking — but it’s a gift, and I wouldn’t change it for anything,” Fox said. “People like Chris have been there a lot for me, and so many of you have. It’s not about what I have, it’s about what I’ve been given — the voice to get this done, and help people out.”
