"Family members confirm that she's been rehearsing for this role since the age of three and they look forward to seeing her fly," Williams said as a childhood photo of the Girls star dressed as the fairy-tale character flashed across the screen. He never mentioned he was related to the actress, and remained completely professional.
Williams' 26-year-old daughter reacted to the news earlier that day by posting the same Peter Pan kid pic on Instagram. She wrote: "Thrilled to be playing Peter Pan Live on NBC in December. I've been rehearsing for a REALLY long time."
Christopher Walken was also confirmed to play Captain Hook in the TV special.
Do you think Allison Williams is right for the role?
