The closing credits include outtakes with the cast and crew, including a moment when Sylvester Stallone goes into his Rocky (1976) persona mid-scene. In the ending, we see audition tapes of Daryl Sabara and Alexa PenaVega for the original Spy Kids (2001) movie.
There are no opening credits or company bumpers, only the message "GLASSES ON".
Alan Cumming appears as Fegan Floop in an extended prologue to explain how to use the 3-D glasses, and when to take them on and off during the film. This prologue is not included on the 2-D version of the film.
