The Vampire - S1-E4
Revealing mistake: In one scene, stock footage of a Boeing 747 flying is used to show Kolchak flying to his destination, and there is no commercial airline livery on the aircraft, just "Boeing 747." This footage was of one of the first 747's built.

Continuity mistake: At the press briefing, Lt. Matteo is standing next to Kolchak with a tall reporter in a gray suit standing behind them, but the next quick long shot shows the reporter in the gray suit standing between Kolchak and Matteo.
