When the two factions of Hondo's pirates are fighting each other, the ones who sided with Maul and Savage are using blasters that fire red bolts, while the ones that stuck with Hondo shoot blue bolts. When Hondo persuades the traitors to work for him again and they attack the two Sith, all of the pirates' blasters are now firing blue bolts. This is Star Wars, not G.I. Joe, and weapons don't just change colour like that.
Commander Colt watches Domino Squad do their test and says, "Start the Citadel challenge, version THX, variable 1138," which is a reference to THX 1138, another film by George Lucas.
