There’s an old saying (attributed to Stanislavski) that, “There are no small roles, only small actors.” (One might argue that writers do sometimes create small roles, but that’s another blog post and not really what Stranislavski was getting at. He meant actors must take any role seriously, no matter its size.)
What I have today approaches the smallest possible actor in the smallest possible role. Despite this being seven years old, I think it still holds the title of “World’s Smallest Movie” — at least until we can make one starring nucleons or quarks. (I especially like the electron banding; that’s quantum mechanics in action.)
For a Wednesday Wow, a movie starring a single atom.
