My pleasure,i've been enjoying many of your past release since years and it's only fair.
As you know there seems to be severals french editions with differents bonus.
The "opening" collector edition have 30 minutes of interviews with Wes Craven, Neve Campbell, Courteney Cox and Skeet Ulrich made by a french journalist during Gerardmer festival.If you still want it....
For the "film office" it seems there is 2 edition with differents bonus :a featurette for the 1st (no details so far ,it's a very old dvd but give me some time to look for infos) ,a short documantery (around 20 min) for the 2d edition wich cover the first 3 movies.
I'll get back to you as soon as i got more infos,hope it helps.
