Nieves Navarro,Nadia Cassini,Carmen Russo in L'infermiera Nella Corsia Dei Militari (1979)

In this film, Cassini is a singer/showgirl who poses as a nurse to recover some stolen paintings, which for some reason are hidden in a military insane asylum.Lino Banfi (who else?) plays the head doctor. He's hot to get in the new nurse's panties because his own wife (Nieves Navarro) is both frigid and perpetually naked. (He tries to give her a Chinese aphrodisiac at one point, but his plan goes awry and he ends up being cuckolded bothby Alvaro Vitali and a delivery boy who's even more unattractive than Vitali or Banfi). Vitali, wearing an afro fright-wig, plays a painter who I think is one of the patients, but he is somehow able nevertheless to land Carmen Russo (a real-life Italian version of Jessica Rabbit) as his nude model. (I think this movie sets some kind of record for casting really hot women and really ugly guys). Rounding out the cast is future porn star Karin Schubert as the mistress of Cassini's art thief employer.
