Just watched
Interrabang (1969) and what can I say?
Well it's a rare suspense giallo which is appropriately titled!
"Interrabang a rarely used, nonstandard English-language punctuation mark (‽) intended to combine the functions of a question mark and an exclamation point.The typographical character resembles those marks superimposed one over the other."
I wouldn't recommend this to every giallo fan but it's good fun for people who like suspense gialli (like myself).
The cast is minimal and the setting is the coast of a sunny island.
I especially enjoyed seeing Haydée Politoff (pictured above) in this and the great soundtrack by Berto Pisano.
