Continuity mistake: After Mr. Palmer walks over and tries to pick up Claude Mulvihill's gun (which Jack kicks away) we see Jack's hat on his left. In the next shot as Jake picks it up it's now on his right. (01:19:40)
Continuity mistake: At 1972 Canyon Drive before Jake meets Katherine Cross, the dried flowers in the vase behind the sofa have been rearranged since we saw them at the beginning of the scene. (01:53:20)
Continuity mistake: After Jake walks threw the door at 1972 Canyon Drive the mirrored makeup case in front of the staircase moves between shots. At first the top is angled slightly, then when we see it again it's opened fully and straight up in the air. (01:48:10)
Continuity mistake: At 1972 Canyon Drive, Jake speaks to Evelyn Mulwray and there's a dress lying on the open suitcase behind her as she sits on the couch. In previous shots, it's not in the suitcase, and no one went near it. (01:52:20)
Continuity mistake: At 1972 Canyon Drive, the shadows on the left stairway wall change radically between shots as Jake walks in. (01:47:40)
Continuity mistake: At 1972 Canyon Drive, Jake sits down and says to Evelyn Mulwray, "Do you know any good criminal lawyers?". If you look closely the dress on the chair to his left has been rearranged between shots. (01:48:45)
Continuity mistake: At 1972 Canyon Drive, Evelyn Mulwray says to Jake after he walks threw the door, "Have you slept?". The pearl necklace she's fiddling with is over her collar in one shot and under it in the next. (01:47:45)
Continuity mistake: Jake takes Lieutenant Escobar to Curley's house, and the flower pot on the ledge and the shades in the window move between shots after he walks up to it. (01:56:55)
Continuity mistake: Throughout the scene at 1972 Canyon Drive, the handle on the hat box to the left of the sofa changes in relation to the hat sitting on top of it. (01:50:55)
Continuity mistake: At 1972 Canyon Drive as he talks to Evelyn Mulwray, the curtain above Jake's head extends almost halfway to the center of the rod. Earlier when we first saw it, it was pushed all the way to the left side. (01:48:40 - 01:52:20)
Continuity mistake: At Ida Sessions' house, Lieutenant Escobar shows Jake the photos that he took at Echo Park earlier in the movie. If you look closely though, Katherine Cross never holds her hat in front of the bridge as we see in the third photo. The other photos also have problems. (00:14:10 - 01:41:40)
Continuity mistake: Jake takes Lieutenant Escobar to Curley's house and as they drive up, he takes his right hand off of the backseat of the car. In the next shot both of his arms are leaning over the backseat. (01:56:00)
Continuity mistake: Jake goes back to Evelyn Mulwray's house only to find the gardener working in the back yard. As he walks over to talk to him the shadow on the circular brick walkway goes from half shaded to totally shaded between shots. (01:46:05)
Continuity mistake: At Hollis Mulwray's office, the shadows on the pictures to the left of Russ Yelburton's door fall to the right of the pictures as Mulwray's Secretary walks in to see him. Two shots later, as she walks out of the office, the lighting has been changed and the shadows fall behind the pictures. Later the first shadows return. (00:51:20)
Continuity mistake: After Jake slaps Evelyn Mulwray, the vase on the table on the right of the sofa disappears between shots. (01:50:35)
Continuity mistake: At Ida Sessions' house, Jake's tie has been retied and his collar changes if you look at them throughout the scene. (01:42:30)
Continuity mistake: After his altercation with the farmer, Evelyn Mulwray drives Jake home and he pulls out a piece of paper with Jasper Lamar Crabb's obit on it. This scrap of paper is not the same one that he tore out of the newspaper in the restaurant before he met with Evelyn Mulwray. The side of this scrap of paper is even, but if you watch as he rips the newspaper in the restaurant, the tear moves to the left as it goes up the sheet. (01:14:20)
Continuity mistake: John Huston sees Katherine Cross and says to her, "I'm your grandfather," and we see a black car passing by them on the road. In the next shot, it's gone. (02:05:15)
Continuity mistake: Jake spots Hollis Mulwray's glasses in the pond and the gardener goes in to fetch them. At first we see the glasses sitting on a rock in about six inches of water with hardly any seaweed around them. In the next shot he reaches in about two feet of water and pulls out the glasses encrusted in seaweed. (01:46:35)
Continuity mistake: As they are escorted out of the Mar Vista rest home, Jake kicks Claude Mulvihill in the stomach and if you look closely his hat never leaves his left hand as he smashes his head into the front railing. In the next shot as Claude drops his gun to the floor we see the hat on the ground next to it. (01:19:10)
