An interesting commentary of the times is made when Mary Servoss remarks to her daughter Faye Emerson that with the housing shortage as it post World
War 2 it was a patriotic duty to house folks if someone had a spare room. Faye
poopoos the idea until the charming Zachary Scott comes along with limp and
suitcase and tells Emerson that the limp was a 'souvenir of the South Pacific'.
After that Scott is invited in. If Danger Signal were remade today a different
reason would have to be found for Scott to gain access to home and hearth.
But that's Scott's business. He's one charming seducer of the female sex and
would have a career playing such. When he gets their money he murders
them.
He concentrates first on Emerson, but she's seen a bit too much of the world
and then he focuses on younger sister Mona Freeman. But the police authorities are closing in so he has to work fast.
If this seems to borrow a bit from Alfred Hitchcock's Shadow Of A Doubt,
Danger Signal is a reasonaably good facsimile. It's a well cast bit of drama
which could have used a more dramatic ending.
Still you'll find little to complain about.
