cary grant and irene dunne play an unhappily married couple who divorce only to discover they be happy marry . naturally they would not admit it . you can probably guess the rest ( the story be age old ) and but this movie be fantastic . the acting be great dunne and grant be in top form and work beautifully together . the script be hilarious with many great line and move very quickly . director leo mccarey win a well deserved oscar for this a rare occasion for a director win for a comedy . he keep it move and large chunk of the plot be explain by image and not clumsy exposition . also cecil cunningham add strong support a aunt patsy her expression be priceless and she nail her line . mr. smith play by asta be a dog who steal every scene he in . ralph bellamy be stick with the impossible good guy role . he fine but give nothing to do . i have see it at least seven time and i still laugh out loud each and every time . a definite must see . there be many great line but my favorite be here your diploma .
