Audio problem: 1840: During a graveyard scene, the village bells are tolling the hour, but someone forgets to kill the sound effects tape. The chimes strike sixteen-o'clock. Submitted by Jean G

Audio problem: 1897: Quentin challenges Barnabas by pulling a decorative sword from a wall display and pointing it at his throat. Unfortunately, the display wasn't all that well attached to the set wall. Though the camera pans away, you can hear a loud clunk as the piece falls, followed by the loud crash of shattering glass as it strikes and breaks a table lamp. You can also see the actors struggling very hard to keep straight faces as they continue with their lines. Submitted by Jean G

Revealing: 1968: A shot of Barnabas and Julia taken through the small window in the cellar door apparently obscured Jonathan Frid's view of the all-important red light. Obviously thinking himself off-camera, Frid took a moment to clean the inside of one nostril with his index finger. Submitted by Jean G

Revealing: 1967: Roger is late for a meeting because actor Louis Edmonds, forgetting he had another scene, had gone to his dressing room and undressed. Because it's "live tape," the other actors must awkwardly ad lib until Edmonds can throw on a shirt and be hustled onto the set, whereupon one camera zooms in tight on him and stays there. You can hear the stress in the other actors' voices as they stifle laughter. They're trying to play an oh-so-serious scene with an actor wearing a shirt, a tie, and boxer shorts. Submitted by Jean G

Revealing: 1897: Quentin walks away from Trask and exits through the door under the stairs. Unfortunately, that door was undersized, and David Selby was 6'2" tall. Quentin bangs his head on the doorframe hard enough to produce an audible thump. Submitted by Jean G

Revealing: 1967: Dr. Woodward struggles with a stuck zipper on an oxygen tent. When the prop refuses to cooperate, he makes a disgusted sound and adlibs to his companion, "Zip that up, will you, Julia?" Then he hurries out, leaving a bewildered Julia to deal with a supposedly critical patient. Submitted by Jean G

Revealing: When "Dark Shadows" did its version of "Dr. Jekyll & Mr. Hyde," the Hyde character, John Yaeger, had prosthetic nose trouble during a fight scene. His rubber schnoz came unglued and nearly fell off. He was subsequently given a nose job. Submitted by Jean G

Revealing: 1990s: When Barnabas and Julia time travel into the 1990s, they find Mrs. Johnson's body tied to a tree. While a crazed Carolyn accuses them of killing her, the "corpse" blinks several times. Submitted by Jean G

Revealing: 1967: The dying Dr. Lang fumbles with a reel-to-reel recorder, making a tape that we'll hear over and over again later on. Only he "records" his message with the machine turned off: the reels aren't moving. Submitted by Jean G

Other: 1967: A persistent fly insists on clinging to Barnabas' forehead as he plots to kill Dr. Hoffman. He tries to ignore it, tries walking briefly out of camera range, then comes back and tries shooing it away on camera, but it keeps coming right back. Submitted by Jean G

Other: 1969: David blunders his line to Cousin Amy: "Don't feel too bad, Amy. I don't like to feel my relatives, err, I don't like to see my relatives." Submitted by Jean G

Revealing: 1966: Elizabeth is thwarted by a set door that refuses to open when she tries to make her exit. She struggles with it, tugging several times, but winds up just standing there, exasperated, until the scene ends a few merciful seconds later. Submitted by Jean G

Revealing: 1795: When an angry Lt. Forbes rushes out Collinwood's front door and tries to slam it, the flimsy set door not only doesn't slam, it bounces back open. The supposedly in-a-hurry lieutenant comes back and gently re-closes the door. Submitted by Jean G

Revealing: 1970: When the sheriff knocks, Jeb opens the antique shop door and the jangling shop bell falls off and crashes to the floor. They pretend that nothing happened and go on with their lines. Submitted by Jean G

Revealing: 1967: The apparently miscued Burke enters the foyer set through a door and starts across the stair landing. You can then hear the director say, "Try it again," and he turns, goes back out the door and comes in again. Submitted by Jean G

Other: 1968: When David and Amy discover Quentin's sealed room, the youthful performers forget to stop on cue and skip to lines from their next scene. The view cuts to Liz and Roger in the drawing room, but the voices of David and Amy excitedly continue from the set next door. Submitted by Jean G
