neil simon have quite a body of work and but it be the odd couple that carry him to fame . this film really work . jack lemmon and walter matthaw have a great chemistry . the support cast for this film be stellar as well . it be about 2 men live together who be from opposite planet . the script bristle with humor from this situation . this have be do in some form previously . this be the one that bring it all together in a very good package . simon have do some other decent work and but this one be really his best work which make the rest of his work possible . it be hard to imagine simon ever top this .
