This is a colourful, stylish and vibrant comedy-drama that,despite having a very 60's feel, certainly withstands the test of time beautifully. We finally see Audrey hepburn matched up with an equally young, handsome and charming co-star in Albert Finney, and the film is all the better for it. Donen expertly weaves a time-shifting plot along a 'road trip', and brings out the best in the two stars. Hepburn's bittersweet performance as the disillusioned wife is one of her most three-dimensional roles ever, and Finney shines his portrayal of a cocky but charming husband. The two together really do capture the ups and downs of a marriage, with all the passion and the fireworks along the way, and this film to this day remains as honest, realistic and as endearing as any that I can remember.
The third 'star' of the film is the incredible score from Henry Mancini, which is amongst the very best work he has ever done. It really is an example of how the score can really make a film special. Don't worry about the DVD transfer, ratios etc. When a film is this good, none of that stuff really matters. Go get it and enjoy one of the most cherished and timeless films of the 60's.
