Limited edition of Lars Von Trier's monument in uncensored version is hard to find. The uncensored Director's Cut is a version that lasts 1 hour longer than the theatrical version, goes further, is more controlled, and much more extreme too. The MK2 Director's Cut edition also includes an exclusive interview with Philippe Rouyer ("The longer it is, the better it is") comparing the two versions for 27 minutes, as well as various interviews with numerous collaborators and actors.
The box set is particularly worn, but the two films can be viewed without issues (I watched them again just before putting them up for sale). Contact me for any sales outside France.
