“Barcarolle in Yellow (1975, released in Italy as "Barcarolla in Giallo"), starring Eva Chantry.
This lurid but stylish Italian thriller is set in Venice during the filming of an eponymous exploitation film, with the lead actress credited as "playing herself". In the day it was critically panned by highbrow critics as "yet another entertainment for those who relish scantily clad ladies being murdered in grisly ways, trippy camerawork and nonsensical plot twists" and relegated to the relative obscurity of other "video nasties".
In the ensuing decades, this giallo has attained cult status, fondly remembered for its bold photography, ambiguous subtext, and of course the tragic circumstances that surrounded the production. Rumours abound about alternative endings that were cut from the theatre version, either by the Italian censors or the American distributor, with bootleg Betamax copies commanding high prices online.”
