Basically my all time favourite movie. If you have ever traveled alone and met a fellow traveller and instantly found friendship and companionship and developed a unique depth of understanding between you and that other person in a small fragment of shared time, then you'll understand this movie so well. The pairing of Bill Murray and Scarlett Johanssen is pitch perfect - their interactions are believable and relatable. On the one hand the movie is laugh out loud funny, and on the other it is so deeply touching. I can't count how many times I've watched this film, it seems to get better with age.
