"The Ultimate Matrix Collection" was later also released on HD DVD (5 discs) and Blu-ray (6 discs) in 2007 and 2008, respectively. The HD DVD release added a picture-in-picture video commentary to the three films and the extras that were missing from the previous DVD compilation. The Blu-ray release presented "The Animatrix" in high definition for the first time. A pared-down set dubbed "The Complete Matrix Trilogy" was also released on HD DVD and Blu-ray (3 discs each), which dropped "The Animatrix" and some of the special features.
