Continuity: When Jack and Helen Hunt enter the restaurant on their trip, a certain song is playing. (I can't recall what song). Jack leaves to buy a jacket, returns, and just after they are seated, you hear the female band leader say, "Here's a special song for (blah blah blah)..." And it's the same song they played 10 minutes ago.

Revealing: At the beginning of the movie, when Jack Nicholson catches Simon's dog, he holds it away from him, with his arms stretched.  When the dog begins to pee, you can see that the urine is coming out from Jack Nicholson's glove.

Visible crew/equipment: Early in the movie, Jack Nicholson walks for the first time to the restaurant in which Helen Hunt works. As Jack turns the corner on the sidewalk and walks towards the camera, he is surrounded by extras playing people he must dodge. If you look in the center and right background, you will see New York spectators standing in the middle of the street, watching the movie being made.

Revealing: Midway through the film, Helen Hunt is on a bus heading to Jack Nicholson's apartment in Manhattan. She is going to tell him that she won't sleep with him after he has given her son free medical care. She is in a pensive mood and the camera pulls out showing her in the window. As the camera pulls out further, the readable sign on the side of the bus says "not in service."

Continuity: In the end when Jack and Helen are kissing, his arm is around her neck. This arm changes from one arm to the other in a split second.

Continuity: When Carol and Melvin are in the restaurant in Baltimore, she is mad at him and he tells her to sit down. When the camera is on her, her hand is on her hip but when the camera cuts to Melvin, her arm is down over her stomach or in some other position during the scene.

Continuity: In the restaurant scene with Jack and Helen, when she is taking her drink from the bar to their table with the help of a waiter, when she first picks up her drink there is very little in it, but when she takes the drink from the waiter and places it on the table it is practically full.

Continuity: Simon's cut on his lip is quite visible in the car on the trip down to Baltimore and on the way back to New York, but it miraculously disappears while they are staying in the hotel in Baltimore.

Continuity: When we see Melvin's bedroom, when Simon is looking for the dog, the shelf above his bed is half filled with books and bottles of water. By the end of the phonecall with Carol, the shelf is completely filled.

Continuity: After Simon has to dismiss his housekeeper, she is leaving the apartment with her large purse in one hand and several carrier bags in the other. She then lifts her hand, which is now empty, and says, "But who's going to walk Verdell?" There was no time for her to shift or drop her purse.

Continuity: Before Carol takes a bath she tries to help Simon out of his shirt. In spite of being handicapped by his cast he insists on doing it by himself, although with difficulties, but he would never have managed to get out of his black pants into his jammie shorts between shots.

Continuity: When Carol tells Melvin off for trying to teach Spence manners Spence is standing in the kitchen. When the camera angle changes as Carol walks back to the kitchen counter Spence is standing in the background holding on to the door to the living room.

Continuity: When Carol and Melvin are talking in her restaurant and he is trying to convince her to go to Baltimore, she folds up her thank-you letter, but the subsequent shots show the many-paged letter is still open in her hand in the lower left of the screen.

Continuity: When Simon's picture is unveiled, the model's hand is now not in either of the positions mentioned in the earlier mistake about the model's hand moving.

Continuity: When Melvin is chasing the couple away from "his" table the flowers in the vase on the table are red and orange. When he sits down, there is now a large pink flower in there too.

Continuity: After the trio's arrival in Baltimore Helen Hunt is in her room placing a call home. When she is first pictured placing the call she has a pager clipped to her jeans. It is gone, never to reappear, in the next shot.

Continuity: When Simon comes to Melvin's apartment to tell him that he has found his dog and Melvin tells him not ever to knock at his door, not even when the smell of a decaying body is emanating through the door so that he has to put a hanky to his face because of the stench, the glasses he is holding in his right hand disappear and reappear between shots.

Continuity: Simon has a rack of pool balls on his coffee table. When Melvin is telling Simon about the bacon, the 2 ball (solid blue) is near the telephone. In the next shot, the dog jumps up to get the bacon and now the 3 ball (solid red) is near the phone.

Continuity: Jack Nicholson is sitting at his desk at home. He takes off his glasses and he stands up to look through the window. When he is about to look outside, the camera shot outside his apartment shows that he takes off his glasses again.

Continuity: When Melvin and Frank are talking about taking Simon to Baltimore the flowers on the table are yellow and red. When Carol is reading her note to Melvin, they're orange and purple. The colour isn't off because Carol's top looks the same as before.
