Okay, to appreciate this film you have to have the right mind-set going in. It's not a 'classic' Hepburn movie a la 'Roman Holiday', or 'Sabrina', or 'My Fair Lady', although it IS better than 'Green Mansions'!
The plot is unimportant, and some of the scenes are just ridiculous; but, that is what makes them fun. The whole movie for me is when they are all in a tiny euro-car driving through Paris, and Audrey Hepburn's 'princess hat' is sticking out of the sun-roof; funny!
I wouldn't spend too much on this one, but it is still a funny, sweet comedy with some great little moments.
