Continuity mistake: Pilot: The mud on Dr. Quinn's face alters in size and shape between when she is meeting the Coopers and when she is upstairs in the room looking into the mirror. (00:09:00)
The Library - S3-E5
Other mistake: Dr. Mike spots a charred Bible within the charred piles of books, and heads into the church. The Reverend is giving a sermon on morality, and offers Dr. Mike the floor and she briefs about certain stories in the book, which would be considered scandalous, without mentioning the book's title, then hands it to the Reverend who agrees such stories are scandalous, until he turns it over, to see that its 'The Holy Bible'. Being a Reverend, he should know The Bible cover to cover, but reacts surprised or shocked over the mentioning of the scandalous stories. (00:36:00 - 00:41:00)
Continuity mistake: When Michaela and Sully appologize to each other at the end of the episode, in the first shot, all of Sully's hair is behind the blue headband. In the next shot, his fringes are not underneath the band anymore. (00:45:30)
Plot hole: In the ending scene, Mike has a probable concussion from her fall, so Sully keeps her awake to prevent her slipping into a coma. They talk all night, reminiscing as Mike experiences periodic pain spasms. Their talk ends with discussion over them having another child, and then they instantly engage in an intimate moment, which would be impossible, considering her condition, and without further checkup from another doctor. Sometime later she is suddenly feeling 'cured', and they return home.
Factual error: Marjorie's tragic death: The Quinn family has her funeral in the town cemetery, where she did not belong, instead honoring her death with a vigil, then transporting her body back to Boston, to be buried properly with her Quinn relatives: A common respect reserved for dignitaries; which technically the Quinn family was/is, and soldiers.
Other mistake: In the scene where Dorothy decides to join the church picnic (just before her operation) Grace is talking to her and hands her a glass of cider as Robert E. approaches. The sky is partly cloudy, but the lighting changes slightly during the shot, and at one moment, appears too bright on Dorothy just before she sets the glass down and walks away.
Continuity mistake: Jake is ordered to remove the children (Colleen and Brian) from the courtroom, and escorts them outside. Yet as Dr. Mike resumes her protest to the judge, Jake is suddenly back in his frontal seat as Bailiff.
Continuity mistake: The gown Gilda S. Claire wears at her open concert is not the same one Emma made for her in the Mercantile.
Visible crew/equipment: Shadow from the boom is visible above Sully when he's talking with Michaela about Jake's condition. (00:27:26)
Factual error: Grace sings "Precious Lord Take My Hand." The song wasn't written until the 1930s.
Visible crew/equipment: You see an automobile's headlights driving in the background when Hank is giving Dr Mike a hard time after his NaNa is brought to the clinic.
Revealing mistake: When Rankin is gored by the white buffalo, in his last closeup the wood plank and steel posts are visible at the back of the animal head prop, at the right side of the screen. (00:44:30)
Visible crew/equipment: After Cloud Dancing leaves to search for the root and Dr. Mike gets the medication for Sully's pain, when it cuts to Jake and Birch talking inside the barbershop, the reflection of filming equipment is visible on the windows. (00:16:50)
The Great American Medicine Show - S1-E8
Visible crew/equipment: While Myra is lying on the table before her surgery Dr. Mike tells her she's almost ready to begin, then just as Horace is about to stand up the orange T-mark is visible on the floor. (00:38:30)
The Healing - S1-E5
Visible crew/equipment: When Loren is at the clinic talking to Dr. Mike about the "little pain" that started from lifting the piano, the shadow of the moving boom mic is visible on the wall and door. (00:09:45)
The Healing - S1-E5
Continuity mistake: Before Loren's operation, when Dr. Mike shows Jake how to administer the chloroform, she holds the bottle in her left hand and the rag in her right hand, but in the next shot both items have switched to the opposite hands. (00:21:20)
Visible crew/equipment: When Kid Cole removes the noose from Jon's neck and helps him off the horse, in the next overhead shot there are multiple T-marks visible on the ground before the shot fades out. (00:37:50)
Continuity mistake: When Dorothy is doing laundry, she grabs a large piece of linen from the washtub, as Dr. Mike approaches and they talk about Dorothy hiring a caregiver for Loren, during his stroke. As Dorothy starts cranking the linen through the wringer, she stops to protest to Dr Mike about it but then turns around holding the wrung linen in her hand, though she hadn't finished cranking it out. (00:32:30 - 00:33:20)
Visible crew/equipment: When Sully visits Mike at the clinic, after dark, to console her over Dorothy's health condition. Watch as he moves past the window. You can see two control room blue screens in its reflection, alongside a boom mic, and the shadow of a long-haired crewman, who stands up, and then sits back down. Though the camera moves behind a potted plant on Mike's desk to conceal it all.
Continuity mistake: Belle's horses change in the end. At the hideout she leaves on Thunder and later is back on the brown horse she started with.
