Robert (author of Distant Relatives) here with more info from Cannes. The Palme found another strong competitor with Aki Kaurismaki's La Havre. Probably the highest profile director from Finland (if you know him from anything it would probably be 2002's The Man Without a Past), Kaurismaki has been off the scene for five years. His return takes him to the French town of the films' title and a couple who attempt to help an illegal immigrant who's being pursued by a tough cop. The Playlist's Kevin Jagernauth notes the rapturous applause that greeted the film and says it "now matches The Artist for the biggest, most rousing crowd-pleaser of the festival."
Meanwhile director Bertrand Bonello had perhaps the least desired spot in the fest. His film House of Tolerance about the comraderie in a brothel mixed in with heaping helpings of violence and sex opened the same day as The Tree of Life. But having little attention payed to it, may turn out to be a good deal for him. MUBI has a good rundown of the mixed critical response to the film.
