The Dreamers (2003, Fr/It./UK)

In director Bernardo Bertolucci's NC-17 rated film of sexually-explicit discovery and intimacy set in the summer in Paris in 1968:

• the scenes of the growing closeness between uninhibited, naturally buxom Isabelle (Eva Green) and her fellow cineastes - her own possessive, brooding twin brother Theo (Louis Garrel), and American cinema student Matthew (Michael Pitt)
• the memorable scene of the trio's 9:28 minute dash through the Louvre (in homage to a similar scene in Godard's Band of Outsiders (1964) (aka Bande à Part) with Anna Karina and her two suitors) - beating the film's time of 9:45, followed by Matthew's acceptance (with a spliced-in clip of the classic "One of us" scene from Freaks (1932))
• with frequent total nudity during the trio's sexual games in the kitchen, bedroom and bathroom, interwoven with play-acted homages and clips to classic moments in cinema (Queen Christina, City Lights, Top Hat, Breathless, etc.)
• the so-called "blood-on-the-face" scene, Isabelle was - surprisingly - shown to be virginal, when she stripped herself down, and was deflowered (and bled) by Matthew on the kitchen floor - in Theo's presence; after they finished having sex, Theo touched Isabelle's forehead and thigh and brought up his fingers covered in blood - and then Matthew also took some of the blood from her broken hymen/vagina and smeared it onto her face as he ardently kissed her
• the threesome's sharing of a bathtub (with their faces reflected in three separate mirrors), and the discovery of Isabelle's menstrual blood seen on the water's surface (a symbol of sexual awakening?)
• the twin's dare ("proof of your love") to shave Matthew's pubic hair; he strenuously objected: "You're both f--king crazy....This is what you call proof of love? Turning me into a freak?..."; when the two called it just a game, Matthew still refused: "Is this something you do to each other? You want to shave my pubic hair? You want me to be a little boy for you? A little prepubescent Theo at six, who you can play games with? You can touch peepee...I'll show you mine. You show me yours"; although he called his criticisms loving, he cruelly noted that he was through with their game-playing, and that the two twins must grow more mature: "You sleep in the same bed together, every night. You bathe together. You pee in the john together. You play these little games. I wish you could step out of yourselves and just look...I look at you, and I listen to you and I think - you're never gonna grow. You won't grow like this. You won't. Not as long as you keep clinging to each other the way that you do"; he proposed to take Isabelle on regular dates - something she had not experienced before

Isabelle's Failed Group Suicide Attempt

• at the end of the film, they were sleeping together nakedly-intertwined in an indoor tent, and unbeknownst to them, Theo's and Isabelle's parents briefly entered the apartment and found the disturbing sight, but did not wake them; a concluding self-destructive streak was exhibited by Isabelle (in homage to Bresson's Mouchette (1967, Fr.) about an abused girl) after she realized her parents had seen them - it was an unsuccessful attempt to commit group suicide by connecting a hose to the gas outlet, and extending the hose into the bedroom
