The NBC Nightly News anchor reportedly took the night off to watch his daughter, Allison Williams, star in Peter Pan Live!, the three-hour live broadcast of the 1960s musical.
Lester Holt filled in on the Nightly News, and E! News reports Brian Williams will be back at his post for Friday's broadcast.
Even though Peter Pan is showing live, there's no studio audience, according to E! News. But Brian Williams is still going to be as close to front and center as he can possibly be during his daughter's showtime.
"We will be watching the broadcast — immediate family only — sequestered in an undisclosed location — close enough to the production as to burst through the stage door the moment the credits roll," the famous anchor told TVNewser.
As for Girls star Allison Williams, the preparation to play Peter Pan has been "so fun."
"I can only imagine what the next couple of weeks and months are going to bring. I cannot wait," she said when she began rehearsals for the role.
"We're so excited about the live part of it," she added. "I think that's what makes it so fun."
The role of Peter Pan is traditionally played by a woman in drag. In the 1960s production, Mary Martin played the titular character. Allison said she grew up watching that production and had always dreamed of playing the part.
"I have wanted to play Peter Pan since I was about 3 years old, so this is a dream come true," she said. "It's such an honor to be a part of this adventure, and I'm very excited to get to work with this extraordinarily talented team. And besides, what could go wrong in a live televised production with simultaneous flying, sword fighting and singing?"
