Special features are curiously lacking, with a series of short featurettes all presented in standard definition. The deleted scenes were deleted for good reason. Interviews with director Robert Rodriguez, the returning stars of the earlier Spy Kids movies, and Ricky Gervais are not very illuminating but might be fun for fans. The “How to Make a Robotic Dog” and “Spy Gadgets” featurettes are very short and not likely to inspire repeat viewings from even the most rabid fans of the franchise. In addition to the 2-D and 3-D Blu-ray discs, there is a standard DVD and a Digital Copy disc included in the combo pack. And it should be noted, the film’s theatrical “4-D” scratch-and-sniff Aromascope gimmick has not been reproduced for the Blu-ray release.
