This episode had to be re-modified for reruns due to 9/11. In the original airing, while Q-Rex roars, it knocks down a couple of buildings with smoke and explosions on scene. In the post-9/11 version, it closes with a shot of the Q-Rex standing behind buildings with some smoke. Shout! Factory also mentioned that the original uncut version of the episodes were apparently destroyed, making the chances of the release of the original uncensored version look bleak.
