Revealing mistake: Joe is much too old to be in high school. He appears to be in his thirties (the actor playing him was 35 at the time).
Continuity mistake: When Quinlan is with Joe Grandi at the bar, Quinlan breaks his sobriety while seated at a round table, but in the last overhead shot the table is rectangular. (00:57:00 - 00:58:25)
Continuity mistake: When Major Pollock sits down at his table in the dining room, he takes the napkin's ring off and after it falls he places the ring on the table and the napkin on his lap, but when John says, "Good morning," the Major's napkin is rolled in its ring and back on the table, then it's gone again. (01:35:00)
Visible crew/equipment: While Raynar and Einar are arguing about the wench, a crewman surreptitiously sneaks in a mic at the bottom left of the screen. (00:47:54)
Continuity mistake: When Scottie (James Stewart) visits a bookshop to question its owner, the book display in the shop's window changes between the time he enters and exits the store. (00:33:50)
Continuity mistake: David Hackett is talking business organizing ranch business while his brother Ed is leaning on the counter, gawking at the beautiful Clee and passing her cloth. He has his right arm up in the close-ups, but the left arm up in the wider shots. (00:04:55)
Continuity mistake: Lucy storms out of Michael's car; the car has the hood (almost) entirely in direct sunlight, but when he opens the door to give chase to her it's mostly covered in foliage shadow. (00:06:40)
