I thoroughly enjoyed this film. It was hilarious, well acted and had a good story. The chemistry between Walter Matthau and Jack Lemmon is a joy to behold. I've watched it over and over again and it still makes me laugh. It is a very underated movie and takes some beating in enthrallment factor. Jack Lemmon and Walter Matthau reluctantly meet up again after many years apart to attend the wedding of their respective son and daughter. A hilarius journey ensues with the old enemies getting lost, losing Jack Lemmon's suitcase and being arrested before they finally reach their destination. It is full of little sub plots which make for an extremely entertaining film. This is a definite buy.
