Braff: I'm Zach Braff and I wrote, directed and acted in this movie and Natalie --
Portman: Merely acted.
Braff: Natalie was my star.
It totally underscores the reason this film stuck with me. Braff knows just what to say, has impecable timing, and seems like a genuinely "nice guy." This exchange also proves that at least some of the on-screen chemistry between Braff and Portman was genuine.
