This is pretty amazing. Some kind soul has created a video featuring the earliest roles of some of our big stars today. My main takeaway: it's possible that Jack Nicholson has actually become less creepy over time. And Zach Braff in a 1980's Woody Allen movie? What?
I am a bit surprised it didn't include Sigourney Weaver and Jeff Goldblum in Annie Hall, but I guess you could make an entire video just of debuts in Woody Allen films.
