Joined by fellow costars Christopher Lloyd and Tom Wilson (Biff), Michael stumbled forward while bowing to Tom, but fortunately fell into the sofa cushions. Despite the initial shock and concern from the audience, Michael quickly regained his energy and showed no signs of being affected.
From TMZ:
Michael recently revealed he falls kinda regularly now ... he spoke at length about it recently with CBS, and they actually aired footage of him nosediving on the streets of NYC. He says Parkinson's is hindering him more and more each day.
It was pretty sad ... MJF said he didn't think he'd live past 80 due to his Parkinson's, but despite this reality, he keeps putting on a brave face and keeping a good attitude.
That was clearly on display this weekend as he had nothing but smiles and good vibes for his adoring fans.
Despite enduring one of the most challenging diseases, Michael J. Fox continues to forge ahead. God bless him for his resilience.
