The unexpected casting of Tony Curtis as the presumed Boston Strangler, Albert DeSalvo, is only the first of the attractions of this hard-nosed suspense picture. Although the style of The Boston Strangler looks dated today, with its split-screen experiments and post-Bonnie and Clyde permissiveness, the film still has the clean, strong lines of a methodical policier. For the first hour, we don't focus on the Strangler, instead following the Beantown cops (led by Henry Fonda) as they track down leads; the best sequence is the near-accidental connection made between burglary suspect DeSalvo and the killings. Director Richard Fleischer had a forceful hand with true-crime material (Compulsion, 10 Rillington Place) and he takes an unblinking look into the then-taboo subject of sexual pathology. Curtis's physical transformation into a dumpy, dull-eyed brute is the best aspect of his performance; it's a role he lobbied hard for, but it did not lead to more challenging work. --Robert Horton
