Oddly, this 17 minute DVD extra is listed on IMDb as being 105 minutes long--making it a feature-length film, which it is not. Instead, it's a "making of" documentary that is included on the DVD with the exceptional film, THE ORPHANAGE.
For the most part, it's a nice little addition--giving insights into the original film (the film makers seeing it as PETER PAN from the standpoint of the parents missing their kids) and the special effects used to make the film. Excellent and well worth seeing provided you first see the feature. The only negative, and it's a problem with all films of this type, is that too often the film and its comments are too self-congratulatory--which makes sense as this is basically an extended advertisement.
