I thought Maggie Cheung was very good in Clean. Acting in three different languages is no mean feat, and on top of that it was a very unusual role for her compared to what she's been cast before. A former drug junkie trying to pick up the pieces of her life after prison and attempting to build bridges with her estranged son.
(Perfect for the Yellow Ribbon Project. That is, if the authorities can stomach a film that references 80's punk rock culture, shows a legal system that lets drugtakers off relatively lightly, illustrates alternative lifestyles with humanity, and manages to convey feelings without sinking into melodrama.)
Possibly the most interesting thing about 5x2 (Cinq Fois Deux) is probably the reverse chronological order. Francois Ozon's latest starts with a divorce and ends with the first meeting of the two protagonists. Suddenly every gesture, word and incident takes on additional weight.
