Seems like a few weeks ago, someone was asking exactly what Cesare said
to Alan when Alan asks how long he has to live. The English title
insert says "Til dawn".
I found an article about Hans Heinrich von Twardoswski in a recent issue
of "Film-dienst" magazine in which that scene is discussed. According
to the article, Cesare's answer is "Bis zum Morgen". (The article is
called "Von Caligari bis Casablanca, Der vergessene Schauspieler Hans
Heirich von Twardowski".) If anyone wants a copy of the article, let me
know. It includes a photo of von Twardowski and Fern Andra in "Genuine"
