Visible crew/equipment: After Central Control announces the countdown for Red Arrow project is now operating, when it cuts to the tower the order is given to "begin photographic alert procedure," and in the next shot a human finger (with a long polished fingernail) is visible behind the seated male marionette, as he leans forward. (00:04:45)
Continuity mistake: When The Hood drives his van off the broken bridge whilst escaping the police, watch carefully; the van bounces off the rocks on the other side and starts to fall roof-first into the river below. However, when it cuts to the van falling into the water it falls in upright. (00:42:00)
Continuity mistake: Before Jeff pushes the button on his desk to activate Operation Cover-Up, you can see there is a dark blue line around the edge of his sleeve, but in a close-up of him pushing the button, the line has disappeared. It reappears in the very next shot.
Revealing mistake: In the shot that shows Jeff Tracy reading a newspaper, the date shown on the paper is 1964, however, the year the series is supposed to take place is in the mid to late 21st century.
Character mistake: Tim Casey is a Colonel, but Scott refers to him as a General in one scene.
Continuity mistake: When the hood parks his car to watch the first Red Arrow crash, there is a white and pink car parked beside him. When he leaves, the white car is still there, but has changed parking lanes and the pink car is replaced with a red car.
Continuity mistake: In one zoomed out shot of Virgil standing beside the tower with the Thunderizer moving closer towards him, he is no longer wearing his raincoat.
