Richard Linklater’s Before Sunset (B) reunites the spontaneous lovers played so memorably by Ethan Hawke and Julie Delpy in Before Sunrise. This time the conceit is that the roving conversation (this time in Paris) plays out in real time. It’s a bit more experiment than narrative continuation and only occasionally nails universal truths as before. But rarely do you get films with emotions laid this bare, and it’s fascinating to watch what Jesse and Celine will do next.
