Anderson is as much a diorama designer as a filmmaker. Not surprisingly, Anderson has been described as a "hands on" director. His particularity extends to his actors. If one watches all of Anderson's films, they'll start to see some familiar faces time and time again.
Bill Murray is a comedy legend, but he's also (in)famously mercurial. Though he's not above a quick payday, Murray is often selective about the projects he works on. This makes it all the more remarkable that Murray is the most frequent collaborator with Anderson.
Murray has appeared in every of Anderson's films since Rushmore – the only one he's absent from is Bottle Rocket. His roles range from central figures (The Life Aquatic With Steve Zissou, The French Dispatch) to minor, entertaining cameos (The Grand Budapest Hotel).
