David Niven and Mitzi Gaynor, two talented actors, are miscast in this stagy comedy about a married couple whose past catches up to them just before they celebrate their wedding anniversary. The addition of a new to the household television set is the catalyst for a series of not terribly funny mishaps and lots of arguing. The dialogue is trite and stilted, especially coming from the mouths of the child actors, although all concerned sound as though they're reading their lines directly from cue cards. Had the film been shot in colour, it might have livened things up, but as it stands,the black and white photography just adds to the dreary proceedings.Happy Anniversary bubbles like flat champagne.
