This one is simply a gasser and is among my absolute favorite FS
movies although I've seen it the first time only a few weeks ago. Great music (the scenes in which the theme is sung are of course the greatest) a marvel appartment and as much orange as in no other Sinatra movie
The other actors are fine too, e.g. Frank's funny "father" or of course Jill St. John...
Unfortunately it is one of them films in which the German synchronisation of Frank is annoyingly unsuitable. So I long for the original version and hope that it will be available on DVD sooner or later.
