A bit late with this but Mondo Macabro recently released American exploitation director William Rose's 1973 Italian thriller The Girl in Room 2A which features Rosalba in a supporting role. A pretty decent example of 70's explotation Italian cinema this movie has a little bit of everything - horror, mystery and of course gore and nudity. The film doesn't have a lot of the great stylistic flourish that was in the better gaillo from this period, but does have a couple memorable moments.
It stars former Mrs. Italy Daniela Giordana, who is also featured in an interview on the disc extras. Producer Dick Randall was also behind Don't Open Till Christmas (also from Mondo Macabro) and the infamous slasher Pieces.
