Compared are the R-Rated Fassung and the NC-17 Version, both released by 20th Century Fox.
The American Matthew mets the siblings Isabelle (Eva Green, who became the Bond Girl Vesper in Daniel Craig's debut as James Bond in Casino Royale) and Theo in Paris in 1968. The movie loving teens are doing lots of things and Matthew lives in their appartment when the parents are out of town. They start some sexual experiments but tensions are being build when a relationship between Matthew and Isabelle grows.
Due to several explicit shots, the Uncut Version was rated NC-17 in the US. That's why the milder R-Rated Version lacks more than 2 1/2 min of footage with sexual content.
Running time R-Rated Version (credits excluded): 1:47:01
Running time NC-17 Version (credits excluded): 1:49:47
3 scenes with alternate footage whereby the NC-17 Version is longer
= 166.5 sec / 2 min 46 sec

A moment later, the R-Rated Version ends when Isabelle pets Theo's butt and back with a feather duster. Theo's waving hand can be recognized better here.
