I love this kind of documentary. This is because it's always fun to watch the cast and crew talk about their experiences filming a particular movie and working with their co-stars as well as the crew of that particular movie.
This is one of the four featurettes on the DVD of The Mask, and one of the shortest of them. It consists of interviews, clips of the film(the majority of them used for comedic and/or ironic effect, and it works), behind the scenes footage(basically all of it being from her audition tapes) and pans and zooms on still photographs.
