Lupe Ontiveros revealed to Terry Gross on the National Public Radio show "Fresh Air" that she didn't know her character was supposed to blow up the Oxman home at the end of the film. Todd Solondz revealed that part of the story only after she had signed on to the film and was on set.
When Consuelo was cleaning the floor while Mikey was asking her about her family, the amount of dirt on the floor changes twice when the camera is turned away.
What are the differences between the R-Rated and Unrated Version?
A
The MPAA initially rated Storytelling as NC-17. However, as this rating hardly allows movies to be shown in cinemas, the producers also handed in a censored version which then got the R-Rating. The censoring in this movie was rather special as no cuts or alternative footage were used. Instead, big colored rectangles were put over the picture. A detailed comparison between both versions with pictures can be found here.
