Mae Clarke is a revelation as a prostitute in the original "Waterloo Bridge". The film was eclipsed by the 1940 remake starring Vivian Leigh and until recently this earlier version was unavailable. This pre-code version holds up beautifully and is better in many ways because of its frankness and because of Mae Clarke's ferocious performance. Kent Douglas plays the 19 year old soldier who falls in love with the prostitute, not realizing her true profession.The movie seems more realistic than the remake because, Douglas looks and acts like a callow 19 year old,and Clarke is very believable as the prostitute who tries to protect her soldier lover from the truth about herself. Neither Clarke nor Douglas became major stars and you can see that they lack the larger than life glamour of Vivian Leigh and Robert Taylor who starred in the remake.However, Clarke and Douglas add a touch of realism which was a hallmark of many of the pre-code movies and which wouldn't be found in American movies in abundance until the 1970's.
