If you have tissues handy, you might want to grab them, because the trailer for writer/director Tim Blake Nelson's Anesthesia is one of the most heartbreakingly beautiful things you'll see all day. The drama's ensemble cast includes Kristen Stewart [1], Sam Waterston, Glenn Close, and Corey Stoll (among many others) and tells the story of what happens when a tragic, unforeseen event in New York City brings a group of strangers together. Watch the trailer above, and check out the latest photos of Stewart [2] on the set of the new Woody Allen [3] movie.
