Captain Obvious Aesop: Gosh, who knew that grown-ups can sometimes behave more childishly than their kids?
Visual Effects of Awesome: The moment where Nancy pukes over the table is superbly well-done, because Kate Winslet had to say her line "What lack of interest?" and then throw up in the same shot, which they did by having her conceal a small amount of fake puke in her mouth (so she could talk) and also run tubes up her body and jaw which could squirt out more fake puke, and then cover up the tubes using CGI.note In stage productions of the original play, this effect has been done by running tubes from an offstage "puke tank" into the on-set sofa, which the actress playing Nancy then attaches to a tube running up the inside of the sleeve of her costume. When she needs to puke, she palms the end of the tube in one hand and claps her hand to her mouth, then they run the pump and the puke appears to spray out her mouth and between her fingers. Polanski did essentially the same thing, but was able to do without the hand-over-the-mouth trick.
