In the useful commentary provided on the DVD reissue of "Three Daughters" auteur Candida Royalle explains how personal this project was for her. Tale of a family with matriarch Gloria Leonard (excellent in a supporting role), whose 3 offspring have romantic encounters including especially the sexual initiation for teen played by Siobhan Hunter is warm, positive and pleasant, in a way contrary to the stereotype (and unfortunately actuality) of the lion's share of Adult Cinema.
With her husband Per Sjostedt as producer and uncredited ass't director, I may not be far off in finding the movie in a similar vein to Ingmar Bergman's family sagas, e.g., Fanny and Alexander, but without the genius filmmaker's powerful dark side dealing with guilt and sexual repression. Siobhan as Michelle is a breath of fresh air in the lead role, with fine acting by her older beau Robert Bullock, and always tasteful sex scenes (explicit but mainly shot from softcore angles). Ensemble cast of mostly East Coast talent does a fine job, and the photography, shot in Deal, New Jersey, is quite striking, making use of seaside locations.
Some info of interest from Candida is that this was the costliest of her Femme productions, budgeted at nearly $100,000 for its 4-day shoot and that she dedicated it to her friend Laurien Dominique, who died tragically while Candida was writing the screenplay (I recall making many a phone call to industry figures ranging from Paul Thomas to Ron Jeremy when preparing Laurien's obituary for Variety newspaper on deadline). Also, it was the most popular of her releases back in the day, putting Candida on the map as an Adult Cinema director.
