“A Pigeon Sat on a Branch Reflecting on Existence” is a truly delightful film from Swedish director Roy Andersson. Not that it didn't fit right in with the dark and depressing 2014 Venice Film Festival, where Andersson won the Gold Lion. He starts right off with three “meetings with death.” These short tableaux set up what is to come: many other tableaux, mini-films that are like paintings coming to life. Andersson is an artist of the Wes Anderson ilk by way of Jacques Tati: He clearly has thought out each detail, the production design as much as the writing.
