Jack-Jack Attack is a 2005 computer animated short film produced by Pixar based on their film The Incredibles, and directed by Brad Bird. Unlike many of their previous shorts, it was not given a theatrical release, but was included on the DVD release of the film. The idea for this short came from an idea for a scene originally considered for inclusion in the film The Incredibles; it was cut from the feature and subsequently expanded into this short. The short is based on the baby, Jack-Jack, and takes place at around the same time as the events of the main film. From The Incredibles, the audience knows that Jack-Jack's babysitter Kari McKeen started experiencing difficulty with him shortly after hanging up the phone with his mother, Helen Parr (also known as Elastigirl or Mrs. Incredible).
