Kristen Wiig - at the end of the digital short "Zach on Set"

The digital short focuses on Zach:

Zach Galifianakis gets some serious screen time.



Simple and funny. A lot of people banded together to make it happen...

Film Zach Drops By The Set :

Zach Galifianakis
Anthony Anderson
Brian Williams
Jack McBrayer
Jane Krakowski
Jeremy Sisto
Mehmet Oz

And I think I saw Kristen Wiig in the audience at the end.

Plus the TLI dudes most likely did the shooting and chopping (editing).

Enjoy!
