Here is what we said about it a few years ago:
WALK ON THE WILD SIDE – Harvey again in another lulu from 1962 and one of the best trash classics ever, as directed by Edward Dmytryk with that pounding Elmer Bernstein score and that great credit sequence with the prowling cat. (Jazzman Jimmy Smith also had a hit with this theme). Laurence Harvey, as expressionless as ever, hunts for his lost love Capucine in the bordellos of New Orleans in the 1930s, from the well-known novel by Nelson Algren. The movie is quite tame though but the cast are fascinating: young Jane Fonda as Kitty Twist, on the road with Harvey and later in the cat house owned by Barbara Stanwyck who wants haughty sculptress Capucine for herself. There is something fascinating about Capucine, I just like watching her. Anne Baxter has a supporting role here as Teresina, the Italian café owner, who would like Harvey to stay on with her. It all comes to a steaming climax at Stanwyck’s cathouse … one to savour then.
