I caught “Paris When It Sizzles” on TV recently. Pretty sure it’s the first (and only time) I’ve ever seen a Perfume credit. Seems this was done at Ms. Hepburn's insistence.
The picture is ... not good or as The New York Times commented at the time, it’s “a rockhard chestnut that is hard to savor or swallow”.
Hepburn however is flawless as always and it’s set in Paris so who’s to grumble?
Seriously though - it’s a terrible film.
