Forever Knight (1992) - 94 mistakes in entire show

Factual error: As the creepy "Nightcrawler," master vampire LaCroix taunts Nick via his CERK radio broadcasts, which Nick listens to on his Cadillac's car radio. Except, CERK's studio sign says it's an FM station. And Nick's Caddy, supposedly a '62, still has its factory radio (we get lots of good close-ups of that), which in 1962 was strictly AM. So how was he receiving LaCroix's station?

Factual error: The police call-radio added on to Nick's old Cadillac (along with a handy dandy detachable dashboard police light and a siren) somehow managed to work for all 3 seasons without an antenna.

Factual error: Though she wore medical smocks and occasionally a baseball cap to hold back her hair, Natalie was never correctly attired when she performed her autopsies. In fact, she usually worked with her hair loose and hanging down over the corpse, which may have made her look prettier, but is a serious breach of forensic etiquette that could contaminate the evidence. Even the best-coiffed coroners still have to wear sterile caps and gear.

Factual error: The Cadillacs (all three of them) used throughout the series to play the part of Nick's sea-green, large-trunk vampire transportation were not, as claimed in the show, 1962 models. Nick's car, in all its incarnations, was actually a '61.

Factual error: The murderer works for a blood bank and drives a bloodmobile, a plot holdover from the first pilot ("Nick Knight"), which was set in Los Angeles. This second pilot, however, is set in Toronto - and Canada doesn't have mobile blood units.

Revealing: When Natalie shows Nick the murdered museum guard's bite wounds in the morgue, the "dead" man's carotid artery is pulsing quite healthily.

Continuity: The blood stains on Nick's white turtleneck are lighter, then darker, then lighter again, and migrate to different positions, both during his fight with LaCroix in the abattoir, and throughout the hospital scenes afterward.

Factual error: The murder victims, all Catholic, are specifically said to have "all worn crucifixes." But the jewelry Nat hands Nick as evidence, the cross that burns his hand and the necklace Magda later gives him are all plain crosses, not crucifixes. (The former is unadorned; the latter has a Christ figure on it.)

Visible crew/equipment: When the parish priest is preparing for the Easter Pageant and gathers up the bundle of sticks, the microphone dips into the shot at the top of the screen. (Aired version only. Mistake was digitally removed on the dvd.)

Continuity: While he's in the confessional, Schanke's raincoat collar is turned up. When he rushes out to confront Nick, it's folded neatly down again.

Factual error: The doll that supposedly belonged to Erica 300 years ago is too obviously modern, with a plastic head and body and nylon hair.

Factual error: Vampire Erica commits suicide by sitting on a park bench at sunrise. Nick and Schanke are called to the scene only a short time later, or so we're led to believe, yet it's still fully dark when they arrive. No sunrise in sight.

Continuity: Schanke calls Nick to tell him they've found Mrs. Hedges' body, and says, "They cut her throat, man." We even see a brief shot of the bloodied corpse. But later in the morgue, Nick says, "She was asphyxiated, right?" and Nat agrees. The corpse on the autopsy table now appears to have an intact throat. So, which way did Mrs. Hedges die?

Revealing: The flashbacks to 1228 in this episode portray some of the same events - Janette seducing Nick, LaCroix making Nick a vampire - that are also shown in "Dark Knight." But here, Nick, Janette and LaCroix are all wearing completely different costumes.

Factual error: In the flashback sequence, Janette calls the immobilized Nick "an immovable feast," a play-on-words reference to Ernest Hemingway's novel, "A Movable Feast." But this flashback is set in 1916. Hemingway's book was written in the 1950s.

Continuity: When Nick breaks into the old Chinese herbalist's warehouse, he twists and breaks a doorknob lock. But when he walks through to the inside, there's a latch-and-bar array instead of a knob. It's a completely different door.

Character mistake: Nick asks Janette if she's ever turned anyone else into a vampire - an odd question, considering the fact that he already knows she has. He was there when she brought the baroness across in the 18th Century flashback sequence for "If Looks Could Kill." It's even odder that Janette tells him she's never done it, since she knows that Nick knows she has. Apparently, the only one not in the know here was the scriptwriter.

Continuity: Elizabeth the leper is wearing a dirty gray dress under her black cloak - until Nick makes her a vampire, when suddenly there's a beautiful, spotlessly clean white gown under her cloak.

Continuity: Nick's beard is fully grown in the beginning of this episode, but it changes, disappearing entirely more than once and then reappearing in various stages of growth, even in sequences supposedly occurring on the same night.

Plot hole: Nat thinks Nick is becoming more human because he can see himself in the mirror, and he replies, "Only sometimes." This line contradicts series canon, as "Forever Knight" did not adhere to the vampires-don't-appear-in-mirrors cliché. Nick was seen to reflect very nicely, in fact, every time he passed a mirror, and not just "sometimes."
