Other mistake: The sheriff drives a hard top, solid roof police car yet he wears a motorcycle cop's helmet.
The Leeches - S1-E4
Other mistake: David Vincent arrives at the airport and a sign says "Welcome to San Diego", but the episode takes place in Arizona and references Arizona-related locales: Tucson, Maricopa County, etc.
Other mistake: After being shot in the air traffic controller's office, the alien disintegrates, but the black residue remaining afterwards is out of position from where the alien disintegrated.
Other mistake: The Invaders' computer announces David Vincent has "sandy" hair, but Vincent's driver's license states he has brown hair. His license also says he has brown eyes, but the actor playing him has blue eyes, and the computer says he's 5' 11", even though one of the Invaders entered the 5' 9" info from his license into the computer.
Other mistake: In the introduction to this episode, actor Roy Thinnes mistakenly says that the guest actor, Burgess Meredith, played the Joker in the "Batman" TV series. Meredith actually played the Penguin.
Task Force - S2-E16
Other mistake: After David and June escape towards the hill, an alien with a silenced revolver exits the farmhouse, but there is already a puff of gun smoke in the air before he begins shooting at them.
