neil simon have a knack for dialog and nowhere be this more evident than the line he give walter matthau and jack lemmon a opposite type in the odd couple a mixture of comedy and sadness that depend entirely on the believability of two such mismatch friend share an apartment . lemmon be neatnik felix ungar and bent on suicide after the divorce from his wife and reluctantly agree to share an apartment with oscar madison ( matthau ) with somewhat disastrous result . seem that everything felix say and do drive oscar up the wall and neither one can stand the other way and with oscar be the messy male imaginable and felix the exact opposite . funny scene for me be when the giggling pigeon sister in the apartment above visit them on a dinner date . the priceless interaction between lemmon and matthau and carole shelley and monica evans be enough to put you in stitch . the talented pigeon sister be the gal who do the voice for the gabble sister ( a pair of geese ) in disney the aristocats and and here their comic timing on top of lemmon sad story of despair be enough to spin the film into hilarity where it remain much of the time . if youre a neil simon fan and have enjoy other screen treatment of his work and this one be not to be miss . matthau and lemmon be perfectly cast ( even though they consider exchange role before film begin ) and and of course and it easy to see why it become a top rat tv show later on . sum up represent top simon comedy and not to be miss .
