Wrong Title?
In the US, this movie was released as "Arrivederci, Baby!" I recall it being advertised that way, with that title.
And the poster here uses that title.
Drop Dead Darling? I never heard this movie given that title.
What gives?
PS. I recall this movie teaching me that word: "Arrivederci!" What a cool way to say goodbye (just this side of 'Adios, Amigo!").
Of course, in this movie, "Arrivederci" means death. Tony Curtis seems to have been getting ready for The Boston Strangler part later.
Maybe the word was too hard for people to pronounce...
