"The Rattlesnake", a 60 year old comedy, but still enjoyable.
29 March 2014 | by davidtraversa-1See all my reviews

I just saw this film for the sake of it, since being a film from the 40s I may have been in the mood for some nostalgia trip, masochism or whatever. And "You Tube" can be blamed for that since it seems one can find EVERYTHING and ANYTHING in it.

I was pleasantly surprised though, watching a very frivolous comedy, with a dynamic and fast tempo and very good actors, from delightful Maria Duval (incredible Deanna Durbin's doppelganger), to melodic (very good crooner and excellent actor) Juan Carlos Thorry, and the Rossy de Palma of those days, Maria Santos (a scream in almost all her scenes and a scene--stealer too).

There is a homicide committed in the Agatha Christie vein --an upper class private school with the classic trio of severe women chaperon, president and vice president of this VERY moral and respectable institution for young ladies with and incredibly quaint collective dormitory and a handful of pretty starlets playing adolescent virgins...(?!) many of them who, unknown extras at the time, eventually had an excellent artistic trajectory: Analía Gadé, Beba Bidart, Ma. Aurelia Bisutti, Susana Campos and the ballet dancer Alfredo Alaria.

Thorry, the disguised policeman pretending to be a music teacher, must find out who did it. Very lightly treated subject, since it is a frothy comedy. A comedy of errors follows where practically everybody is suspected to be the assassin till the truly unexpected end.

The movie fails in many issues related to any 60 year old film, like in any old Hollywood production, where we find even shocking some goings on that at the time I assume people found absolutely normal in every day life situation, but that for today morals they look pretty prudish and passé (women's liberation seems to have been totally unknown then).

Pleasant enough thanks to the well choreographed ballet numbers in the dream sequences, the lightness of it all, and some very funny scenes in a totally scatterbrained production. Nothing to write home about, but all in all, still enjoyable.
