Visible crew/equipment: The boom mike is briefly visible at the top of the screen when the woman on the horse rides up to Mike and Kyle. (00:06:10)
Revealing mistake: When James' craft touches down outside the Sheriff's office, the wires suspending it from above are visible. (00:33:50)
Continuity mistake: Mike Donovan (riding a horse) is chased by a Visitor shuttle. It is obvious that there were recycled some shots from "The Final Battle" (Ep. 1). In "The Champion", Donovan does not have a laser pistol. However, there are some shots in which he has that pistol: obviously, those shots are taken from TFB.
Revealing mistake: When the two wildcats throw hand grenades at the Visitors, the grenades are obviously fake because the explosions do not occur at the same place as where the grenades land. The detonations have obviously been located in a safe place away from the actors. (00:11:50)
Visible crew/equipment: When Julie says 'We're gonna stand and fight' near the end of the episode, a boom mike briefly creeps into view at the top of the screen. (00:42:15)
Continuity mistake: When Philip is first seen with the metal thing on his lens a buzzing sound is heard. Afterwards, no buzzing sound is heard. (00:17:10)
Continuity mistake: When Kyle is with Donovan in the warehouse shooting at Philip, you always hear a bang coming out of the machine gun but sometimes a fire blast is not seen.
