Before They Were Famous: Guest stars on The West Wing

[Inquisitionist]

Happened to watch 20 Hours in America: Part I recently and was delighted to see a couple of young fresh faces that looked familiar but took me a while to place.  One was Amy Adams, playing the daughter of an Indiana farmer; the other was John Gallagher, Jr. as a lovesick teenager.  Wondering if folks have spotted other young guest stars that surprised them on rewatch.

I knew he looked familiar when I saw him in The Newsroom, but couldn't place him.
