"A New Kind of Love" is a genuinely bad film--something you'd never expect considering it stars Paul Newman and Joanne Woodward. Additionally, having Thelma Ritter for support would also seem to guarantee a much better film. However, despite the talent, the film is terrible--with only a few moments here or there that rise above the rest. The bottom line is that if you have a badly written film, even top stars won't save it.
Paul Newman's character is a HUGE part of the problem. While he's supposed to be a bright and talented newspaper man, he's mostly just a horny guy who spends most of his time chasing women. This is very one-dimensional and makes him hard to like. As for Woodward, she is more interesting--a scared woman who makes herself look far less attractive because of her fears. However, after getting herself a makeover when she's in Paris, he sees her and thinks she's a prostitute--a very expensive prostitute--and that intrigues him. Does any of this sound the least bit romantic? And, does it seem very funny? If your answer to both is 'no', then you see why the film has a lot of problems. All in all, a very disappointing and unfunny movie.
By the way, there really is a Festival of St. Catherines and women really do such silly hats. I assume, however, that most parties for St. Catherines did not involve having Maurice Chevalier showing up to entertain!
