Despite Victor Mature's claim that he never 'acted' in any of his films, he does well enough here. Full of shadows, sly humour and a storyline which keeps you guessing, plus that wonderful soundtrack (including snatches of Over The Rainbow), this stands as a monument to film noir - Betty Grable could clearly handle a non-musical role, Elisha Cook Jnr displays his twitchy vulnerability as he would in so many 40s thrillers. The real-life early deaths of Landis (playing Vicki here in a manner which reminded me of Vivien Leigh's Blanche Dubois, all flirty giggles) and Cregar (superb here as the corrupt detective gliding and purring in that unusual voice like a huge cat) do affect viewings of this film and give the proceedings a hint of sadness. This aside, there is much to enjoy, particularly in the supporting characters of Mature's actor and columnist friends. One niggle though, given the plot dependence on various people letting themselves into other people's apartments, how come Vicki got herself locked out?
