Thousands of years ago an asteroid fell from the sky, creating a huge crater, in thecentre of which a piece of asteroid rock remains.

Once a year, a convention is held on the site, attracting astronomers, teachers, families with would-be teenage astronomers - as well as military personnel.

As the stars begin to align, events occur which are startling, and completely unexpected.

This is Anderson at his comic best; it is also suffused with the grief caused by the death ofthe mother of one of the families - giving the film a profound emotional impact.

The film stars Tom Hanks, Margot Robbie, Scarlet Johansson, and Tilda Swinton, as well asfamiliar faces from Anderson's previous films.
