The timing of this film is unfortunate. It came out in October, 1945--several months after the war in Europe had ended. Had it come out during the war, it would have been an excellent propaganda film for the folks at home. Instead, it just seems a bit odd to come out when it did.As far as the casting goes, it IS unusual. Constance Bennett plays the lead and over the years she tended to play a variety of rich society ladies. Co-starring is Gracie Fields, a British music hall singer and comedienne. It's a strange pairing but it worked..particularly since they de-glamorized Bennett for the part.The story begins just as France is falling to the Nazis in 1940. An American woman (Bennett) and her companion (Fields) are trapped in Paris. They also accidentally come upon a pilot of a downed British plane...and through this help to create an underground organization which repatriates pilots through the course of the war. Naturally, the Germans are more than a bit anxious to catch them. The film's biggest strength might just be because it came out when it did. Instead of snarly, over-the-top Nazis, the Germans in this one are more believable than ones you would have seen in films just a short time earlier. Plus, a restrained performance by Bennett (one of her better ones actually) help to make this an enjoyable and well made film.

Paris Underground (aka: Madame Pimpernell) is a solid British entry in the war/intrigue genre produced immediately after cessation of hostilities with Germany in 1945 by aging, but still glamorous, American star Constance Bennett and distributed in the United States by United Artists. Ms. Bennett, a somewhat flighty American married to a French foreign office official, and her middle-age spinster pal Gracie Fields, while fleeing the city during the fall of Paris in 1940, find themselves by happenstance carrying a downed British aviator in the trunk of their automobile. Turned back to Paris by a German road bock, they have to take the flier back to hiding in Gracie's apartment. One of the best and most suspenseful scenes occurs when the girls have a flat with the pilot in the car's rear, and a Nazi officer stops to assist them! By hook and crook they eventually manage to smuggle the young aviator to Free France. Delighted with their success, they establish and underground railroad that eventually gets hundreds of allied airmen back to their bases. With a combination of American audacity and British pluck, these two brave and resourceful women cause the occupying Germans a big headache. Sharply directed by Gregory Ratoff and atmospherically photographed by Lee Garmes, Paris Underground is tense, exciting, and believable. Acting by the two female leads is first rate with good support coming from Argentine actor George Rigaud as Ms. Bennett's husband, Kurt Kreuger as a suave but cruel Gestapo captain who would like to be more than friends with the ripely beautiful Ms. Bennett, and Eily Malyon as the grouchy concierge of Ms. Field's hotel. Editing is a little untidy in places, with some scenes taking too long to unfold. However, the story is never draggy, but engaging and exciting from beginning to end. Alexander Tansman's florid but stirring score, which drew an Academey Award nomination, drives the action along at a gallop.This picture bears some resemblance to glitzier Joan Crawford vehicle Reunion In France (1942). While not up to competing head-up with that big hitter in the entertainment department, the more staid Paris Underground is somehow more believable and is an enjoyable, inspiring little potboiler in its own right for fans of the war/intrigue thriller.

I pretty much agree with the lukewarm review here entitled "Mediocre war heroine tale." This is far from a "gem," as some people would have it.The plot keeps moving and is mildly interesting, although without finger-biting suspense. We know pretty well how each situation will turn out, the romance, the hair's-breadth escapes, and so on. As the end approaches there is a little surprise, but it's all fixed up within minutes as victory is snatched from the jaws of defeat and medals are pinned on the heroines. Ho-hum. I barely kept myself from turning off the television.Outdoor scenes are all shot in studio and look very fake. The foggy night scene in the fields--puleeze! The music has moments when it goes over the top.Although the movie is set in France, French characters are insignificant, while the American and English ladies are large, ultimately heroic presences. It's certainly a narrow, nationalistic vision of "Paris underground." I did find it refreshing to see a movie, especially one focused on the conflicts of war, in which the lead characters are female.Don't get excited about seeing this. Don't set aside important time for it. But if you run into it accidentally, you probably won't think it's a total waste of time.I believe this film was also released with the title "Madame Pimpernel."

In a late example of a fading Hollywood star going to England for a career boost, delectable Constance Bennett plays a madcap, irresponsible Yankee stuck in occupied France. She's uses her glam appeal to aid the resistance & help Allied troops escape with the help of co-hort Gracie Fields, the Brit Music Hall star in her final screen perf. The whole unlikely enterprise is done with reasonable flair under surprisingly lively direction from Gregory Ratoff and stellar lighting from lenser Lee Garmes. Too bad no one was able to turn the corner for the last act when the film tries for a darker, more serious tone, but it's well worth a gander. As is the still jolie Mme Bennett.
